The adage “out of sight is out of mind” is more fitting in relationships than is “absence makes the heart grow fonder”. Clichés as they both might be, long distance relationships are indeed no cakewalk and need far more effort and patience to maintain than a normal relationship where people live together or live in the same city and meet up often. Long distance relationships are hard to maintain simply because bringing the physical gap of not being able to see each other often, not knowing what the person is up to and even seeing your loved one in the presence of other people is a tough nut to crack! Also, it might have something to do with our attachment styles! 
Your attachment styles can predict the success of your long distance relationship.
We all have specific behaviors, when it comes to romance, which remain unchanged, even if we change partners. Many of us are often dubbed as clingy, or commitment-phobic, or even too independent when it comes to our relationships and basically, it all boils down to our specific attachment styles. 
Attachment styles are simply the way we behave with our loved one, and this behavior of ours then can make a relationship smooth and enjoyable to be in, or bumpy with too much strife and expectations. Remember that attachment styles can change with a big change in life – things like pregnancy, a new baby, adoption, a sudden financial crisis, the loss of a job, an accident or injury. 
Now the thing with attachment styles is that depending on the kind we have or are, and depending on the kind of attachment style our loved on has, is key to making a relationship work, or not!
If you grew up in a warm, safe and loving environment then you are the kind who feels secure in your relationship with your partner, are close to him or her but still respect individuality and independence in a relationship. You are the kind who can be with any kind of attachment type, and most likely to make a long distance relationship work to your advantage as well. 
If you are the anxious attachment type, you are likely to be the one most partners describe as clingy, possessive and even stifling. You often remain worried about the future of your relationship and depend on your partner for your happiness and fulfillment. You might find it difficult to maintain a long-distance relationship as your demanding nature will not find satisfaction in not getting the due attention over the distance. 
So, you are the one who would probably thrive in a long distance relationship for you probably like to keep detached from your partner and may not even consider him or her that important, to begin with. You are likely to come off as cold, distant and perhaps even narcissistic in nature. 
You are the one everyone dubs as commitment-phobic. Being in a relationship is scary enough for you, naming it and establishing concrete boundaries makes you run strike back and be rather moody. A long distance relationship should work for you as well as you basically like some distance between you and your significant other. 
Do the right thing based on you and your partner’s attachment styles to sustain the LDR!
If you’ve already had a failed long distance relationship and fear being in another one since you took that failure personally, well don’t, on all counts. Your failure may not have been your fault or even the other’s, rather it may be a relationship doomed to fail due to different attachment styles. But does that mean that you can never be successful in a long distance relationship, like ever?
Of course not! We all can be successful at anything we so wish to if we only put in a little effort and also change ourselves a tad. Depending on your attachment style, here’s what you need to do, to make it work! And mostly, the work remains the same – trust, patience and a lot of loving attention along with space given! 
- Secure Attachment: You are the kind of person who remains happy and loved in any circumstance of your relationship, distance immaterial. The problem in a long distance relationship will arise if you are with a person who has an anxious attachment type. Your security in the relationship could be mistaken for taking the relationship for granted, so you might need to shower some special attention on your “clingy” partner.
- Anxious Attachment: You need constant reassurance in every relationship and a long distance relationship is particularly hard for you to maintain. If your partner is also anxious-preoccupied, frankly, the long distance may not work out for either one of you for both of you need to remain in constant touch with each other. If your partner is a secure attachment type, then remember that he or she is happy in your relationship and you need not feel abandoned or ignored. Your avoidance attachment partner is likely to be the happiest in this long distance relationship and may need a gentle reminder every now and then that you need attention too.
- Avoidance Attachment: So your secure partner may not be affected by the distance or even the various emotional phobias you have, and in case your partner is also the avoidance attachment type then you guys would probably revel in the relationship you have over the miles. But if your partner is anxious attachment type, Houston, we have a problem! You need to get over yourself and give a little part of you over the phone or the chat to your loved one to make sure the distance does not stress out your already hyper anxious partner. And with the distance, a little more attention should be easy for you to maintain as well.
Remember that all relationships are same only in that they all need work, effort and plenty of love to work. Mostly, if the love is there, you can make it work – distance be darned! That said; a long distance relationship does need that extra bit of effort more to retain the spark for an ending that’s equally bright and happy!
