Is he just trying to sleep with me?

I been recently dating a guy. The dating is very new (only a week) but since then we have seen each other almost everyday. We live close by, so doing casual dates - like walking our dogs, is so convenient.

I’ve seen him 6 times in the last 7 days and for some reason, some of the stuff he said to me isn’t sitting right with me.

Basically we were talking about our dating history and he told me the last two women he dated, he ended their “relationship” (he never asked them to be his girlfriend) because he didn’t feel a connection after about a month. He said it was unfair to them to waste their time. He told me they were very very upset when he ended things, but it was the right thing to do. Yet, it came out that he had slept with them after the third date. Tonight was our third official “going-out” on the town date (not our casual walks or hugs).

Unbeknownst to me, before he told me this, I was talking to him about going to my cottage this weekend with him. I wasn’t planning on sleeping with him, but if things happened then whatever. After I found out about his history, I told him it’s not a good idea we go to the cottage because we will sleep together and we both initially agreed to take things slow.

He agreed and said he would never do anything I don’t want to do or disrespect my boundaries. He assured me he likes me a lot and he wants this to “go in the right direction”.

I don’t know why I just have a bad feeling. Like he wants to get into my pants or after a month he’s gonna do the same stuff he did to those girls. I feel like everything he says to me he said to them, just to get into their pants and dump them.

Does anyone see a red flag here or am I overthinking???
