Am I being a idiot for no reason??😭 advice please

So, I so need to get this off my chest because it makes me so mad 🤬 sorry for the long post.

My boyfriend and I have been together 4 years and live together. He has the most shittiest friends in the entire world, absolute losers. When he goes out with them drinking, he comes balling in at 6AM and drinks so much he is out of control. He hasn't done this one for a while mind you because I locked him out the house because when we had an argument he chose his friends over me and his alcohol. Everytime he goes out, there is always an argument without fail so no wonder I am already hesitant about this coming Saturday.

So this Saturday he is going out with his lowlife friends again. I have conditioned him to coming in at 3AM (This is the time I would come home sometimes, so not fair to make one rule for him and one rule for me). He was okay about this but then he told me he would be going out at lunch time. That is over 12hrs of drinking?!?! We are expecting a baby, due in November and I just feel so annoyed that 1. He will spend a fortune when he is out and 2. He will be drinking for so long. When I used to go out, I would go out at 9PM.

Am I overreacting? Is it because I am hormonal? I just feel he has no god damn respect for me then plays the "I am controlling him" card.

Honest thoughts ladies! Xxx
