Okay here we go again!

I left XH in early October. He's been trying to get back with me pretty much ever since. However, about two weeks ago he's said he's trying to give me some space to heal. Which is fine by me. We talk pretty much every second day, always about the kids and arrangements for them. We've sorted out the property issues which is good too. We're sharing the kids on a fairly hectic roster, but it is working for the kids. Every time I go over to XH's place (a couple of times a week) for changeover, he gives me huge hugs. Up until a couple of weeks ago, when I told him I wasn't really comfortable with that much touching, and was okay with hugs only, he'd be looking for kisses etc too.

Anyway, I went over to XH's house this morning to pick up the kids, everything was normal, XH wanted a hug etc before he left. I packed up the kids and came home.

Alex has been constipated the last few days, so I asked him what he had for dinner last night. "Nothing. Daddy's friend came over". I replied "which friend?" He said "she's a girl." He didn't know her name. She and Daddy ate dinner together. XH has one friend who is a guy, and no female friends, so I have no idea who this woman is. She wasn't there at 6:45am this morning when I arrived.

Don't get me wrong, I'm VERY Happy if XH has someone else. It will really help him get over me (which is an issue - he's really clingy).

However, I am concerned that he might be introducing someone to the kids already. They're only three-and-a-half and fourteen months. I don't mind him having a "friend", I'm not comfortable with a "friend" being introduced to the kids unless it's going to be a long term thing.

Then again, she might have just been a friend, and not anything more!

So what do I do? Do I ask XH who the friend is and why he's introduced her to the kids? What if she's just a friend, and I'm over-reacting? I don't want XH to get the idea that I'm jealous, because I'm definitely not, I just don't want the kids getting confused about who lives where. It's only been two months, which I don't think is enough for children who are this young to be introduced to a new "friend", IYKWIM?

I just don't know what to do.
