When I broke up with my boyfriend, it was at a time when we were both arguing constantly... we were both so in love that I don't know how and where things went wrong.
He decided he wanted a break from me, coz things were getting too much and it was affecting everything else like college work.
We somehow didn't keep in touch much...(he thought I wouldn't wanna hear from him, and I thought it was the other way round) and I'd only get a text from him once every 6-8 weeks....
I felt the worst I have ever done and nothing anyone said meant a thing to me. I couldn't get over him (we'd been together for a year), and would try and keep myself busy doing other things... for some reason socialising with the girls and what not only got me down more, so I gave myself goals... such as focusing heavily on my education, pleasing my family and making them happy (since I felt guilty of devoting so much time to someone like him who didn't seem to care much, and had somewhat neglected my family in the process)...
I started being ok throughout the day, but the minute I got into bed, I would lie in bed crying for atleast an hour every single night, and would cry myself to sleep coz I missed him. Not keeping in touch always made me wonder what he might be doing, if he's happy without me, if he's found someone else... and all the "what if's" used to really bug me. However, thinking back... I would have probably felt worse if I had kept in touch with him, knowing he didn't wanna be with me.
All this went on for a year and a half before we ended up together again, and we have now been together for 2 years, and I'm the happiest I've ever ever been... not so much because I'm back with him... but also coz I'm a new person. The time we had apart gave me time to think about me, and think about how I'm making a difference in the lives of the people closest to me... I learnt to love me and respect me (not in a vain way or anything)...It gave me time to value myself and make myself a better and stronger person...Being back in this relationship, we're both different people, and happier together.... coz we grew as individuals. I'm sure even if we had gone into different relationship - that would be the same... we would be in a better position to be in a relationship and handle it, knowing what things went wrong in previous relationships.
This post probably isn't much use to you... and I'm not saying you'll end up together again (I don't know your situation and what you both actually want from this)...but, try and look at it in a positive light. Be there for the people you couldn't be there for 100% coz you were in a relationship. Be there for you, and use it as an opportunity to learn about you. Each person in this world has so much to give, and I don't want you to waste it all away by crying over someone...try and be the reason for someone else to smile. Whatever happens, happens for the best... so use it to your advantage.
I realy don't know what to say...having been there myself, I can totally understand how no advice will change anything... but thought I would share my little story, and how I tried to get over it all... I hope it makes you feel atleast a little better.
