Love my boyfriend but is it meant?

So when I met my now boyfriend it was instant connection. We love all the same things and he’s way older than me and super calm. I love to see him happy and enjoying life and he wants the same for me. One problem and let me start by saying I don’t want to fall into the finding an issue with every guy type of thing. We have been dating for 3 months and he makes me very happy. However, he’s retired and he’s constantly at the bar if he is not with me. He says he’s watching the games and meets up with his guy friends. I could see this become an issue once we live together because he will want to go and I’m tied down to two children (3,6). Like the other day he came and stayed at my house but he showed up after being at bar with some friends all buzzed. I have had drinks around him and he’s never been rude or mean or even starting fights none of that. I’m coming to glow for some advice not judgement on how I should go about this. A part of me wants a family and someone to come home to eventually when the time is right and I don’t want to feel like something is constantly missing. Am I the one for him? Sometimes I feel people change and do for who they want to? I literally watched my ex go from partying all the time to with his gf now complete dad/husband mode. I’ve seen it for myself and that’s why I’m starting to wonder if it’s just I’m not the right one for him. As well as he may not be the right one for me?
