Do I stay for the kids

I really don’t know what to do I have a 2 year old and 4 month old and I have drifted so far apart from my other half we don’t sleep in same bed haven’t done for nearly a year. He sleeps with me and then sleeps on sofa. I have begged for him to sleep in bed or show me some affection but I honestly just feel like I’m getting used for somewhere to live and for a slave. Valentine’s Day he got me a card that said have a shit day bitch my birthday just gone nothing and Mother’s Day nothing. All I want is for him to show me something. He sits upstairs all day long playing PlayStation whilst I look after kids and when I say all day I literally mean all day. And smokes weed all day long ( I don’t smoke weed and wouldn’t ). I just feel like our relationship is dead but I feel so guilty on the kids if I leave as I always wanted a family that was together and I said when I got pregnant with him I would try everything to make sure we were a proper family.

Please tell me that kids grow up ok without a family together because I’m so miserable with him and I can’t do this any more.
