We've been together for 3 years but she left me for another guy about 4 months ago, and they've been together for about 3 months.. I tried so hard to get her back but it seems hopeless..he cooks for her, takes her out and gives her everything..I feel so useless as a man...I couldn't buy her a lot of things and a lot of the times I'd always be upset the last 1-2 months we were together because I was afraid she'd leave me for another man..I feel like dying right now..I don't think I can ever love again...I improved so much just for her..but it just seems like shes found someone better..shes the only girl I want...how can I get her back...?
