He said we’re in a relationship but it feels like I’m in a situation ship, help?

When I saw this guy, we went on a few dates and I thought things were fine. He was slow with texting. Didn’t love that. Told me he lives with people, I thought he had many roommates but turns out it’s only one person and it’s a woman. Who is also not someone he met through friends or anything. They met on a plane apparently. As the weeks went by I got more worried. He took a trip on a cruise with a different female friend. And I’ve not thought much of this stuff because he wasn’t my bf.

I noticed on his dating app he said he’s looking for something serious. I believed it. We’re in our 20s. He’s late 20s, and his profile seemed to show being serious. Before his cruise and a wedding he went to, we went to get ice cream and he had to leave really early bc he said his friend he lives with had people staying over and they didn’t know how to get in. So I found it upsetting that he just left quick.

he asked me to meet up after the cruise and wedding, and he texted me a lot and seemed interested in talking while away. But as he comes back the meet ups feel weird. Like he said remember we went to this restaurant? We never went. He doesn’t remember details about me. Ex. I have a peanut allergy. He said oh your soy allergy.

I asked him how he’s feeling or if we could be more open. Because he tries to make out a lot. When he first kissed me he grabbed me… kissed my face, walked away. Came back and kissed my lips then left. But emotionally I have nothing with him. We aren’t romantic either. He said; do

you wanna be in a relationship officially? I said ok.

Since then there aren’t even dates. We meet up and do something and say he gets food he wants us to split the bill now… an he only eats it so I say no. He only wants to talk then kiss. he’s been saying can I come over. When I say no he says ok I have to go home early anyway. So we only meet for 2 hours and before we’d meet for several. And just talk. He won’t even text me back often, but he’s still asking about the next plans. I told him the texting bothers me. So my verdict is he doesn’t care and just wants to sleep with me. Idk why he lied about the relationship. There are too many weird things here and this hurts so bad.

We’ve been seeing each other for 4 months and only “official” since like a few weeks. I’m in tears over this for what?
