Update:

So we were talking on the phone tonight, and everything was going ok. But I mentioned that I don't want kids. He seems to "maybe" want kids. And he brushed it off like, "well we're not at that point."

Also, omg, while on the phone, he said "I'm going to put you on speaker phone for a minute." I then heard a toilet seat. So I asked him if he was using the bathroom, and he was like "oops, here let me move the phone and talk to you in a minute." I hung up. Lol. He called back and I asked why he thought that was OK. Like was he just comfortable? Or what? He just said he thought he could get away with it without me knowing. I hung up with him shortly after. Is that strange / inappropriate behavior (of him)?

I'm pretty turned off. I guess that's it.

Edit: No one's responding and I'd really like someone to just tell me I don't have to go out with him and that being weirded out makes sense.
