He's left before?
What a cruel man he is. It's one big head fuck really, with the way he is behaving.
I maintain my earlier advice. Gather your dignity around you, hold your head high and start to move on with your life. Move furniture round, redecorate, buy new clothes, anything to help you feel a bit better at this time.
Do not hold out hope of him coming back, it will be far harder for you, if you do. Find the anger for what he has done and use it to propel you forward. It may not feel like it now, but there is life after divorce and you will be far happier when you're not constantly wondering where he is, what he's doing, who he's with, if he is being honest etc. I'm 2 and a half years on and I am glad it's over now and I've met someone who is fantastic. But if you'd asked me when I was in ylour place, I wouldn't have believed you, I was desolate and distraught and he left me in limbo for 5 months!
Until I made the decision to file for divorce. With help from mumsnet. You can do this. Detach, try and move on and if he decides to come back eventually and you want him great. But at least you're trying to move on.
He sounds like a serial adulterer to be honest. And you would actually be far better without him. You do not want your child to witness this as she grows and think this is how women are meant to be treated
Sounds like lying isn't what he does, but WHO he is!
