Please help

I probably sound repetitive and desperate but I'm having a really hard time. I don't know what to do.

I'm a good person I think. I'm kind and thoughtful. I like the way I look and I don't think I would change myself, I'm happy with myself. I'm living a good life and have many opportunities. My family are all very supportive of me and we're all really close. I have a few really good friends but since I've moved around a lot I miss out on that a bit.

I feel so unwanted by him. I hurt so much all the time. I miss him so much. He ended it with me when he couldn't get an erection. He didn't even wait for me to get dressed. Then he wanted me again but then said he doesn't think he'd be good for me because he's not a clean slate and that he should probably try to find an older woman. He's 12 years older than me. He said maybe we could try sex but not tonight because he's too tired. He hugged me big and said it's so good to see me and said he'd talk soon. I haven't seen him again.

He was rude to me through text and ignored me. He put a new woman in a relationship on his facebook a couple of weeks after he left me and he didn't tell me before he did it. A few days later he apologised to me for not calling and said how he met her and he cares enormously for her. A few weeks after that I told him how I was starting to see someone but that this new guy is only going to be a friend. He started asking me questions about my sex life without him. I told him I would call him and he just answered 'no'. It hurt badly.

It's been a few months and now he's just ignoring me. He said how he'd be there for me and help me out but he hasn't.

I don't want to feel like a worthless person anymore. I don't want to feel like I've done something wrong or that I'm not good enough for him. I don't know if he's ignoring me because of her or if he just doesn't care about me. He can't even say a little hello.

I know he could say unkind things about people and he acted like he was really good and he hurt me so much and I know how an abuser doesn't treat another woman better so forgive me but I can't help thinking he just didn't like me enough to treat me well. He used to talk to me all the time. He wanted me even after he ended it then he just got her. I don't know how he can just not talk to me now unless I'm just not worth it.

I know he hurt me but since he's with her and he's ignoring me I feel that she's better than me and he doesn't want to do anything to upset her, like I'm a threat. Because she doesn't have the age gap that he seemed to have a problem with us being together and if she has a better personality and looks than me then he wouldn't need to treat her unkindly.

Please help me. I feel so alone. I feel like even if I like myself and feel I have a lot to offer he doesn't even want me as a friend or to even say hi to or check up on me. Why is he just ignoring me? Why can't he even say hi?
