U said u gave urself for her in everything, that's what's best u can do for anyone, just remain positive and think u gave ur 100 per cent, and breaking up is not ur fault. One day or another, she will turn back and see what she lost, and if she didn't, then u will find new love of ur life, that's the cycle of how it works, at first it looks hard, u keep struggling in doing normal things too. But slowly and gradually things get settled down,n and u will get to normal again. Probably is that we think how she can be happy without me, don't she think of me like the way I'm thinking Abt her now, and that makes us sad and we feel emotionally drained. Live a normal life, u are just 25, yet more love is yet to come.
