For context, we are NOT big drinkers. We have been together 11 years and have 2 amazing children. We got together when we were young (teenagers) so particular habits I assumed my DP would grow out of. One issue throughout our whole relationship is how awful he gets when he drinks alcohol. This isn't often (Around 3 - 4 times a year, usually an occasion together such as a wedding/leaving do/festival together/birthday). That's probably the reason why it upsets me so much - every nice occasion we have is ruined by his drunken behaviour.
Years ago I asked him to stop drinking as he cannot handle his alcohol. Its slowly crept back in again and I fear last night was the final straw. I do not want to have to tell him to stop drinking, it makes me feel controlling. But equally, I cannot go on like this. It seems so trivial to end a (normally very good relationship) due to events which only happen a few times a year. But I can never "Enjoy" myself on these events because I'm on edge, babysitting him, or apologising for DP behaviour. When he goes out without me, I am also left on edge worrying because he is such a liability (injures himself, stumbles into roads etc).
Last night it was my leaving do, DP had to return home earlier than me. By the time I got home (Around 1am) he had a big lump on his head from falling over upstairs (This is what his brother told me who gave him a lift home) and had urinated all over my dressing table/makeup etc mistaking it for the toilet! I am beyond upset.
Any wise words of wisdom? Any mumsnetters which have experienced similar? As I stated earlier on, it seems too trivial to end our relationship over. However I want to enjoy myself, I don't want to be on edge for special occasions.
