He told me to leave. Which isn't the first time. I stayed for a few days because I thought it would blow over. After a period of time of him verbally telling me over and over that I'm not welcome, bringing dinner home for everybody but me. Making arrangements for somebody to be at the house for our kids when they got off the bus, even though I was still there. I asked him why, he says because he's hoping every-day when he leaves for work that I wouldn't be there when he got back. THEN I left. Like I said, only so much a person can take! So, yes he kicked me out (not by force) but I eventually made the decision to leave. So, however you want to look at it.
So... You left your kids.
And haven't gone to court to establish a current parenting plan.
And then you wonder why you aren't seeing your kids.
You want to see your kids, so go to court and modify the previous orders, etc. You may have to pay child support, depending on what sort of parenting time share that you end up with. Do this sooner, rather than later, or your inaction could result in the current set up being the status quo.
You want your personal effects back. Well, get a place to put your stuff, and ask for access for your stuff nicely but firmly. If he won't turn over your stuff then go to court - assuming the real value of what you seek if worth it, or the sentimental value is great enough to justify it.
