First off, aside from this issue, I'm very happy with our relationship, we do lots of nice things together, have lots of quality time (no children), financially we both do very well, we have a great life together etc etc however...... his drinking has been an issue from day one (don't judge, when you first meet someone I think you can be blind to certain things / you aren't living with it on a daily basis).
He is 37, I am 29, (not planning on children) he loves to party. He goes out drinking almost every day. Parts of it that I'm okay with: he's home early, I know where he is, who he is with, I'm always invited to join. What I'm not okay with: he's a prick when he's drunk! Even after a few drinks he slurs his words, he's impossible to have a decent conversation with, he's unreasonable, in a nutshell he repulses me at night! He's a different person. It is to the point that I am so relieved when he passes out because I don't have to put up with him until the morning when he's sober and amazing again.
The fact of the matter is, it's an issue that has been discussed over and over, he isn't ever going to change is he? What now? If other parts of our relationship were bad then I know id leave, but it's literally just this. Is it 'normal' to have one thing that drives you nuts about your other half? Do you tolerate it because the rest is so good?
