Am I wrong

So my boyfriend like to stay out late every night with his friends. He would tell me he picking them up from work but won’t come back home until 4 in the morning. I told him I didn’t agree with him doing since I have newborn to look after and have to get up early.So last night he did it again I guess he didn’t come back until 5 am and when I woke up an hour later him and his friend was in the living room. It’s weird to me because he spend more tome with his friends then me. He did not use to be like this when we first start dating.
