I'll try and be concise on the history - together nearly 10 years, unmarried, 4 children. Partner is an alcoholic, anger outbursts, laziness etc but no violence. He has a history of gambling large amounts of money, staying out til almost morning etc. In Jan he got caught messaging a prostitute for sex but he didn't go through with it, he left for a few weeks, sobered up, started exercising so I asked him to come home. I tried to make the conscious choice to move on from it - because I love him. He started drinking again, although much less, but still in secret, I could feel my anxiety rising again, like I was just super aware of him lying. Then a week or so ago, he went out when I was ill in bed and didn't come home til 4am, slept in the car and missed the start of the work day. He has left again, and I've told him that's it now, I can't carry on and the messages from Jan still affect me a lot.
Here's the guilt thing - I feel so bad, I love him, my daughter in particular is gutted and is crying a lot, and he's being forced to live with his mum that he has a lot of trauma with and he hates it. Initially he said that there's not much to do, but now he's decided that he doesn't accept my saying its over and he'll do anything to come home even if it takes years. If I'm honest (and I know it sounds pathetic) I like when he says all the nice things via text about loving me and he'll do anything etc, but I am also enjoying the lightness that my house is now, I didn't realise how I was feeling before, but now he's gone, I'm keeping the house clean and tidy, I think I'm having more patience with the children and I just feel a stillness that I'm enjoying... but it still doesn't really feel over. I'm so confused, like constantly confused about what's happened over the years I can't really construct a complete thought about it.
Also it feels like this is the silliest reason to finally end the family I've built, when it's something that has happened so many times, although not a lot recently, and can I really use the fact I feel cheated on as a reason, when I said it would be OK and he can come back? Like it feels like I'm scrounging for excuses for him to be the bad guy or something?
Sorry for the ramble, I feel very alone, but I know he does too and that's adding to my guilt and sadness that I've caused that for him.
