Boyfriend too friendly?

We’ve been dating a year now, and at the beginning of our relationship my boyfriend messaged a girl that he had slept with before and told her to tell him when her six weeks were up so they could have sex again. She had just had a baby.

(I understand this would be a deal breaker for some but we talked about it and I gave him another chance. This post is about what would YOU do, not bashing me and my decision to stay with him.)

Fast forward to last night, it was his cousins party and we all went to the liquor store to get drinks. The girl was coming out the store and he was going in and he gave her a hug and they exchanged words.

He had been drinking and so he blamed it on him drinking and now he keeps telling me I deserve better. I’m upset but I don’t know if I’m overreacting or maybe it was just an innocent interaction. How would you feel ladies?
