name changed but im a regular. coz I'm ashamed.
Been with my partner for 7 years and have 2 DC. Had lots of up and downs over the years mainly drug related (him) and depression (me).
I thought my partner had given up smoking skunk over 4 years ago when I first found out I was pregnant with our first. I knew he'd had "slip ups" but I didn't know (or maybe was in denial) he had actually continued. I definately had no idea he'd been doing cocaine for the past 2 years, including days before DC2 was born and weeks afterwards.
I had no idea he'd been going round to some girl's house to do said drugs. He said it wasnt sexual, nothing happened like that between them she was just somewhere he could do what he wanted (smoke skunk, do a line without having to share his supply coz she had her own wheras his other "mates" always nicked his.) 
Maybe I believe him that nothing happened between them. But it really hurts that while I really needed him (stressful pregnancy, always skint and then colicky unsettled baby) he would rather have spent him time and money hanging out with another woman. A fucking horrible woman who took great delight in telling my BIL who was also her friend at that time what a rotten mum I am, a crap girlfriend and how it sounds like I should have my babies taken from me. She's never met me so only knows stuff about me from what my partner has told her.
It hurts that while I was having nightmares about how I'd have the money to take care of new baby and struggled to buy my unborn baby things he was pissing his money away on drugs and I had no idea.
It hurts that I'm basically a mug. The only reason I know all this stuff is because I finally became friends with him on FB (ahhh yes, FB, the bane of so many relationships) and saw all these lovey dovey "I really can't wait to see you friday night" messages from his bitch "friend". I confronted him and to save his arse from being accused of cheating he told me about his addiction to drugs.
I should also point out I found out about all this after I had moved 200 miles away from everyone I know. I know no one here in the north west. Apart from my partner. I thought he wanted to move here to make a fresh start, becuase we couldn't ever afford to live in London where I'm from. But no. The real reason is so he could kick his habit. It hurts that me and our children weren't enough for him to kick his fucking habit.
Honestly it feels like I've been duped.
Apologies for it being so long and thanks if you've managed to decipher all my ramblings (crying so much of it probably don't make sense).
I don't really want to hear cried of dump the bastard but mainly becuase I'm scared to as he says he would take my babies away from me. to be fair I've been a crap mum to them in the past couple of months since all this kicked off. Back on meds for PND, shouty, insomniac, depressed and weepy. I can't seem to shake the pnd this time.
