Input: So my wife and I have been separated for about a year and a half now. Everything has been very amicable. We have a good schedule with our two boys (ages 7 and 11), we hangout as a family usually once a week, and get along a lot better than when we were married. Things have been working out so well between us that we have not been in a rush to pull the trigger and finalize the divorce.

When we first agreed to separate, one of the things we agreed on, and she brought up first and was very adamant about is that the kids would not be exposed to anyone we were dating until we knew it was a very serious relationship. Something I was fully on board with and readily agreed with. Whenever I start to date someone, I joke with them that we will be married for a couple of years before I bring the kids around them.

The ex has a condo there that she goes on long weekend trip, or for family events, and for part of the kids school breaks. They have cousins near the same age there and I believe it is important that they have a chance to spend time with them.

They pent spring break there, and came back to my place on Saturday. Sunday morning I woke up and started making pancakes for breakfast. I asked them, how were the pancakes, and my oldest replied along the lines of that they are much better than mom's friend Ron. This set off big alarm bells in my head. Namely, who the fuck is Ron, and why is he cooking breakfast for my kids?

I didn't follow up, or ask any questions of the boys, and just got ready to take the boys to the beach. Later, we had to stop at the ex's house so the boys could pick up their backpacks for school the next day. I casually asked about Ron and why he was making breakfast. The ex just shrugged it off that he came by after hockey practice. She gave a little dismissive explanation, that as far as the boys know, he is just a friend. Later that night I texted with her and told her that I'm not comfortable with some guy coming over trying to ingratiate and buddy up to my boys. I also brought up the agreement that no boyfriends/girlfriends were going to be brought around unless it was something that was very serious. She replied that she wasn't sure how serious they were, but the boys just see him as any other friend. I also brought up that if things were getting serious, than we need to fast track finally getting divorced.

Now kids aren't completely clueless, especially they older one. I'm sure they aren't making out in front of the kids, but I also know that lingering glances, sitting close to each other, small signs of affection are there.

So AITA? For getting upset that I have no idea who is hanging around my kids, how much time he is spending with them, what kind of relationship he is trying to make with them. And come summer vacation when they are there for over a month, how much will he be around? I know as a divorced partner, I have no say in who she dates, and I do want her to be happy.
