So I dated this guy for 3 months, and we broke things off pretty much a month ago. First the first half of the time we dated, he was really into me and chased me so hard. I started caring about him a couple months in and then he suddenly got cold and distant when I returned from a holiday. 2 weeks after returning I had known for a while he would leave the country, but we were figuring that if we were serious about liking eachother we could continue this relationship when he came back (he is coming back 6 months later). But in those last 2 weeks he acted horrible, just prioritising his friends all the time and hardly bothering to see me. If I asked for a straight answer he'd try to keep me on the hook and instead complain he had many problems in his life etc and deviate from answering properly.The last straw was when on his final night he arranged clubbing with his friends, didn't tell me it was his last night until the last minute and asked me to come to the club as an afterthought. When I got upset he hung up my phone calls and ignored me saying he didn't feel well (but he still went clubbing). His friend told me that he had said that when he leaves I'm like nothing to him but his friendships are still there so that's why he acts like that. I told him off and said not to contact again, he texted me like 10 times after I didn't respond. When he left he deleted my photo and put a picture with another girl who is really pretty, like I am pretty myself but she is seriously like some model. I feel so bad about myself and inadequate. How do I feel better about myself?
