I've been with my wife for over 12 years and married for 8, we have 2 kids, 6 and 1 year old boys. We've had are usual ups and downs, I've suffered with mental illness and have sought treatment and I'm on medication. I've had the problem all my life, it comes and goes, and puts a strain on the marriage occasionally. Everything was fine, when about 2 years ago, we had a miscarriage. My wife became distant and withdrawn,   And suddenly announced that she wasn't happy and wanted to leave. I was devastated and to cut a long story short ended up paying thousands, my family bent over backwards and somehow I managed to keep the house and lived there with my son (while she ended up at her mothers). I cried, begged, got angry, but all to no avail, this was what she wanted, divorce etc, the lot. I was just starting to get a handle on it, when out of the blue, she said she wanted to come back!?!. I didn't know what to do, but I wanted to be a family for my son so I took her back, my family didn't approve at first, but gradually they came around. We fell pregnant again and everything was good but Over the past year my mental health problem had got worse, I'd been fired from my job, but we had another boy ,and we were ok, ticking over, i was getting help etc. She fell in with a group of other mums from are sons school, and begun hanging around with them ALOT, it was all barbecues and drinks, for hours on end, and she got completely drunk once (which I'd never seen her do) Recently her grandfather died who she was very close to, she went away for the funeral.....

....and when she came back, yep you guessed it, she didn't want to do this anymore, but this time there was lots of aggression, anger and spite in her, I'd basically messed up her entire life. She was different, she was texting all the time, round her friends. She said she'd been unhappy for months, I couldn't believe it. I begged her to try again, counselling etc, The separation tries to stay amicable, but if anything doesn't go her way she flips out and says things that really hurt me.

It's been just over 2 months, I've lost my house now, I've lost pretty much everything, we share the kids, and now I find out she's seeing someone else WTF!! , I could physically hear my heart break when she told me.

i found a text from her saying she "loves me forever" , 37 days later she wants to end the marriage.

i don't know what to do anymore
