I think I just require a hand hold here..so we have been together a really long time, engaged, have a lovely house and a beautiful 2 y/o DD. To cut a very long boring story short(ish) ..I noticed he had been acting off and a bit distant however he does struggle with mental health issues so it can be like that. He has had a recent problem with going out partying and leaving me to hold the fort, so things weren’t amazing between us because I felt like he was obviously letting me down but ultimately my DD down the most. Things all came to a head last weekend when he lied about going on a work trip to stay out with mates for 2 nights getting on it, we never spoke for days and I told him he needed to leave. He agreed to leave and said he had been unhappy in our relationship and that’s why he did what he did..however before he leaves he tearily tells me that he has been messaging other women for about a year while intoxicated and he wants to sort himself out and see if we can work on things. I know deep down this relationship is DOOMED, but I am so so devastated.. can this ever be fixed? Or is it time to accept the facts and get my ducks in a row
