When do you throw in the towel

M

I feel like I’m at a cross road and idk whether to call it quits in my relationship or keep hanging on. We’ve been together forever 5 years (we’re both 30 now) have been through a lot - unemployment, family drama, personal growth, and I used to think we were good but we keep having several small dumb fights and now maybe once a month a big fight. I love him but the one issue that’s never gotten better is his drinking. I 100% believe he has a problem. He can’t limit himself and goes from tipsy to black out drunk super quick. (I rarely drink) This is when our fights are the worst and it’s gotten to the point to where we just yell at each other no matter who’s around. It’s been a slow escalation too - he used to just be silly and now when he’s drunk he becomes a jerk... yet when he’s sober he’s always sorry and apologizes and thinks it’s not a huge deal. Idk how much longer I can put up with this 😞 but I hate the thought of living without him.

Our lease is up in august and I feel I need to decide what I want to do by then. Break up and buy a house on my own or get couples therapy and try to save the relationship and buy a home together?
