I had my X arrested today

[sleeper]

Another blowup....
After having X arrested back in October for trespassing (refusing to leave my home)I decided to drop the charges. The wheels of justice turn slowly and I was contacted by the city attorney about the case last month. I did this for a variety of reasons, the major one being not to distress the kids as things had settled down quite a bit since last fall.
I have been parking on the street when picking up; kids at X's house since then. I've notice X's H comes outside often when I'm there (now I know why). While dropping off DS the other night i phoned DD to come out so I could see her too and get a hug. As she went inside, X's H came out and approached my vehicle asking if he could have a word with me.
He said I owed him "an apology" for having my X arrested. I disagreed. A little back and forth and I finally told him if he apologized for coming in my house without being invited and cursing me, I would reciprocate. I then got in my vehicle and attempted to close the door. He grabbed the door, pulling it out of my hand and said, "You're on my property now." I ignored him and started the vehicle with the door open. He (seeing he had failed in eliciting a reaction?) then turned and walked towards his house as I backed down the driveway.
I called X to convey my concerns about the children living under the same roof with an individual with such a temper. She said he was trying to protect her (whatever) and that he had seen what she had been through, the counseling, expense of counseling and of getting arrest off her record (attempting now), etc.
I'm just sick of some type of blowup every 2-3 months.
I have since spoken with X who agrees I do have a right (and her permission) to come on the property to pick up/drop off the children. I suspect but have not investigated a legal right also as we have shared custody.
Will the drama ever end?
