My fiancè and I have been together for 3.5 years, we have an 18 month old and our second is due in July. A couple weeks ago he told me he wanted to separate for a bit to focus on himself and being a better dad. Normally this wouldn't concern me as much as it is this time. We haven't slept in the same bed in almost a month, he's still barely helping with our daughter, and his ex is living with us and she's all he seems to care about any more. They keep telling everyone there's nothing going on and she's a lesbian but I'm not buying it. I miss my family being a family and I don't think I can handle living with him for much longer if A she's here and B there's no time frame when he's going to decide if he wants to be with me or if this is permanent. I just don't know what to do any more.
