Boyfriends bad influence friends 😑

I just want to know if I'm overreacting for being kinda pissed off about this really. My boyfriend and I were together 3 years. We broke up for about 6 months. In that 6 months he changed, started drinking every night, smoking weed and all the wild stuff that young guys do etc. Also during that breakup we slept together and I got pregnant. At first I didn't want him back. But things changed and he had the choice to carry on doing what he wants and see the baby in a controlled environment or get back with me to settle down and be a family. Took some time for me to believe him but he kept saying how he wanted us to be a family and now 31 weeks and everything has worked out great. He's not how he was, he really has stepped up to his responsibilities and changed for me and the baby. Couldn't be happier. Now my problem is his 'friends' keep trying so hard to get him to go out drinking and doing crazy shit. He tells them no all the time. They just don't give up. They know he's back with me now and he's going to be a dad and he's chose to stop all that shit and they can't respect that. They might find it hard to believe but some guys actually do just wanr to be a better person for their family. Not every guy wants to drink all the time. Its okay for them, they dont have a baby on the way. Usually I ignore it but after them doing it again last night I'm really annoyed. Am I overreacting or do I have a right to be annoyed?
