I'm hoping y'all could shed some light on a situation.

I started dating this person, D, about four months ago. At first, it went really well. I thought he was really nice. Only a week after meeting me he let me stay at his house for four days when my state experienced an unprecedented winter storm and my power went out. He cooked for me, he was charming, funny, kind- I really liked him.

But there are some things that have bothered me. Namely, earlier this month, he didn't text me for over two weeks. Yes, I could have texted him, I am aware, but since I was the last one who sent a text and I don't like bothering people I didn't. I felt angry and upset that this was happening, because I feel if you're dating someone, which he says we are, you talk to them regularly. He texted me last week saying he was sorry and that he missed me. So we picked a date night and he made dinner and everything; it was actually really nice.

I found out that night, though, some upsetting news: he's moving in with another partner in August, when their leases are up. That's not what upsets me in and of itself; I like her and I am happy for them. I know I could still see him. What bothers me is that he's made this statement a couple of times that he "doesn't want to commit" during the pandemic. Like even though he's dating a few people he won't call himself our boyfriend. Which bothered me a bit, but, okay; I guess I get it. I just felt upset, though, that he wasn't willing to "commit" but he was willing to commit to getting a house with his other partner.

I've been talking to this girl from a dating site, and she's amazing. I complained to her about D earlier this week and she gave me some advice. Then today I was talking with her and she told me she was on the phone with this company and it had been frustrating. I said "Oh, D works for that company," and she was like, "wait....is it this D?" and showed me his profile from the dating site I met her on. I was like oh my god are you dating him and she said no, but he had asked her out on a date on Sunday and she didn't feel like going now. I felt a bit bad about that, like it's my fault she lost interest.

Then she said, though, that she thinks I should dump him, because he's either omitting me out of his relationships or he misgendered me. She sent me a text message where she had asked him if he was dating anyone else, and he said "I am dating two women that I have known several months." He's actually dating me, the girl he's moving in with, and a woman who was his best friend turned partner. So yeah, either he did omit me, or he was referring to me by the wrong gender.

This girl I am talking to, who is wonderful, says I should end it. She might be right. But I am really, really bad at ending relationships when there's still some good things about them and I am not super angry at the person or anything. D is a decent guy. He's taken good care of me. The sex is fun and I like spending time with him. But that text message, on top of ghosting me for two weeks, feels really rotten, and I don't know what to do.

Any advice?
