How to not get upset when I see my ex flirt with my "friend"?

[Elizabeth18]

We dated almost a year and a half and had a pretty good relationship. We were each other's first bf/gf. We broke up at the end of April. He wanted to since I was unhappy towards the end because he wasn't a good bf. He said he wasn't ready for a relationship and got into it for the wrong reasons. He didn't want one and won't until college. I liked him so much and even tho I deserved to be treated better, I couldn't break up with him. He even said he thought I deserved to be treated better than what he could give me. (Never saw each other due to him being busy and tired and couldn't make me one of his priorities). I treated him like a freaking prince. He's 17 and I'm 18.

 

Well he does volleyball and this girl we know does it too. So while we dated they would talk about that and I felt like he kinda liked her. He never acted on it tho. Recently they've connected and she said they stayed up until 5 a.m. talking and he sat next to her in church (he wouldn't for me towards the end). I don't have lovey feelings for him but I get a little jealous/upset when I see how much they talk and flirt. He said he wasn't gonna date in high school so idk if he really does like her but I think he does. Maybe it's all new and exciting for him like it was when he first talked to me? It sucks seeing him have eyes for someone else when that used to be me. I used to be friends/good acquaintance with this girl but then we drifted when she started acting like she was all that. I sometimes wish we didn't date because then we wouldn't be here and I could enjoy him and flirt with him like the other girls do. Our relationship is ruined. I hate how he acts around me. I hate how I fell for a boy when I needed a man. Advice??

 

And he with this other girl in front of me a few days after we broke up. His sister said he liked her. I was upset on how fast he could get over me. So I assume it was either a rebound crush or he liked her while we dated. I think it was the second. He liked the attention

"Maybe it's all new and exciting for him like it was when he first talked to me?"

 

yes it is, soon as I got to this sentence, I thought yes

 

I do not think he will stop at either of you, he is too young to not get tempted, you both like him so he's nice, there are very few men on Loveshack whose numbers are in single figures, move on from this torturous scene, he might yet come back anyway, they do that too, take love slowly
