Not sure if Relationship is worth saving
I've been dating my boyfriend for 2 1/2 years, living together for 2 years. We bought a house together 1 year ago. Over the past year he has been drinking more and more, now about 5 or 6 nights a week. Mostly at home, unless we go to dinner or out somewhere. I have spoken to him about this several times and expressed my concerns about his health, the quality of our relationship etc.. He says he knows he has been drinking too much and will slow down, but he hasn't. Every weekend he sleeps all day and will not do anything active. This drive me crazy because I have always been an athlete and when we began dating, he used to go to the gym regularly. Now he is a couch potato and I am miserable. He is very dedicated to his job, never goes in late or calls in sick. He is 36, I am 32. I can't spend my life like this. Can people change or do these patterns only get worse?
