RYL Forums - I REALLY need advice please

So last night me and Andrew got into this HUGE argument, and I got some excellent advice from some very insiteful people. I don't think I am going to leave Andrew, but for now I am going to pull away for awhile, I love him, I can't leave him, but heneeds to change his ways, I will always LOVE him, but that doesn't mean I am always going to be IN love with him.

So, the reason I am posting is not really for the argument we had last night, I have already recieved great support on that issue, but today I get a text message that says "Rachel (His ex wife) says we can stay in her appartment until we find another place" (because we are staying with my parents because the place we were suppose to get fell through). All we have to do is pay electric and watch the kids sometimes (ok, mind you she stays in an appartment that she herself only pays electric on, so its not like she is out any money). But I know what "watch the kids sometimes" actually means, it means that when she says jump, Andrew jumps, and woah la, we get stuck with kids 24/7 while she goes out and gets high, or drunk, and I just don't really think it is very fair for him to be asking me to agree to something like that. I mean I appreciate her offer, but I know its only because we can't keep the kids while we are staying at my mom and dads, and she wants a baby sitter. Oh, yeah and he always said he told her "We can watch them on days Im off and maybe more" ok, who exactly is going to watch them while your gone? I wil watch them on MY terms, when I choose to, I love the kids dearly, but they arn't MY kids and I shouldn't have to drop what Im doing, to watch them. Also, so we are going to watch them on his days off, when do we get time alone? Or are we just going to sarifice that too? The divorce papers say that he gets them every other week and she gets them every other week, and SHE has primary custody, its joint, but she is on it as the primary caregiver, she is the one who gets assistance on the kids and such, so should she be the one keeping them the marjority of the time. When we were living on our own and watching the kids we ALWAYS had at least one of them, she NEVER had all of them, and would get a lot of times of not having any kids. I am just fed up, I need your advice, am I out of line? Should I move in there? (She won't be living there she lives with her new boyfriend) or what? I just don't know...
Any advice is appriciated.
