What you are planning on saying to her sounds good. I do think you should acknowledge her role in this to yourself a little more though. You two not working out in a romantic relationship isn’t all on you. She could’ve been handling her responsibilities this whole time, especially with your added help, but it sounds like she resorts to drinking and basically a “poor me” attitude rather than fixing the problems a lot of the time, and that part is on her. You feeling guilty isn’t going to help either of you, really, and she needs to own up to her own issues and start fixing them, because that’s the only way her life is going to improve, with or without you. You might even be enabling them in a way by putting up with them (and stopping at the liquor store when she wanted a drink), so it might hopefully do her some good for you to separate. Sometimes that’s what it takes to whip a person into shape. I know it worked with me. haha. I’m better off now than I’ve ever been, even though I miss my ex very much. I’ve still improved my life in every other way, and the devastation from the breakup is what started that change.

So maybe try to reframe it in your mind a little bit and it’ll feel a little less hard for you. Sometimes it takes hurting someone to help them. I think it’s good that you still want to help her get back on her feet as much as you can, though.
