Backstory is I found out XH had had an affair last year we separated in the summer (2015) but decided to try and give things another go beginning of this year. It was too difficult for me to forgive and I didn't trust him one iota so 2 months ago told him I wanted to split permanently and have just started the ball rolling for mediation/divorce.
He desperately wants to be back together and the last weekends when he's had the children and I've been alone he keeps finding random reasons to 'pop in' to check up on me
1st occasion he said he'd forgotten a bag of stuff for the kids
2nd again another bag for kids he asked if he could pop upstairs to the loo (we have a downstairs loo) and went through my bathroom bin as he found an old pregnancy test id thrown away (and pushed to the bottom) as I'd been having a big clear out and questioned me over it.
3rd came in to pick up something random for the kids very early in the morning while I was still asleep checked up on me in my bedroom.
4th after promising me he wouldn't just pop in as it sets me on edge he came in last night while I was out and again today and went through my bags and rang me questioning about things he's found. I am so angry.
He's never hit me but he has an anger problem and I've got a wall and a door with holes in from where he's punched them.
He's totally paranoid I'm seeing someone else which I am categorically not, I just want to be on my own which I have told him many times! But he doesn't believe a word I say, he's more of an act first apologise later person.
I rolled my eyes at the first couple of times but going through my bags and bins? He's starting to scare me aibu?
What should I do?
