Dating

Guy I’m seeing regularly hangs out with his ex and has been with her the past week and not responding to me. Should I be worried?

So I’ve recently started seeing a guy who told me he’s friends with his ex’s. At first I didn’t think much of it, I’m not usually the jealous type and thought it was nice to know his relationships had ended nicely and with no hostility. However, he had mentioned that his last relationship ended as his girlfriend at the time had been meeting with other men behind his back. He seems to still feel betrayed by her while still being her friend.
I again didn’t think into it but he brought her up a few times during the two dates we went on, he still has posts up of her and the whole week he has been away on Mexico for work, where she lives and is spending time with her but hasn’t even bothered to reply to me in a week.
I sort of have a feeling that he’s still hung up on her, and that he probably would still want be with her but can’t be since she disrespected their relationship before. I honestly didn’t mind since I don’t get that vibe with his other ex but the fact he has been putting more energy in to her this week then into continuing to get to know me has indicated where his heads at.

I’ve actually already ended things with him over it last night. He read the message within minutes but never even replied. I guess I’m looking for reassurance that I made the right call and that I haven’t jumped to the worst conclusion without reason. I dunno, the last time I saw him we also slept together and I guess I expect to be treated with a bit more care and respect after that since he knows it’s a big deal for me, I don’t have casual sex. And for all I know they’re probably sleeping together, and when I think about the future man I want to see myself with it’s not someone who would carry himself like that or treat me like that. I tried to be understanding that maybe he’s just busy with work but he seems to have time for her, and I only know this because she posted him, he didn’t post her which I feel like is even shadier as he might not want me to know he’d been with her.
