I gave mixed signals, he made me feel pressured, now it’s a mess. What to do?

I accidentally gave a guy mixed signals so I apologized and I explained that I'm new to dating and just want to be friends. Is it rude if he still tries to make a move on me?

In a nutshell, I met a guy at a friend’s birthday party and as we were having lunch we seemed to have chemistry, as we sat there and chatted for 30-40 minutes without pause. He left and I had hoped to get his # because I wanted to be friends, so I asked a guy who had if he’d mind sharing it. I texted him and he was glad, but my mistake (according to my half brother who’s a close friend) was that I didn’t immediately specify I just wanted a friendship. We chatted for several hours at a time for about a week, and I invited him to a neighborhood event.

He took all this to mean I was looking for a relationship, which we discussed. I said I did find him attractive and agreed we had chemistry, however I was very very sorry I had given mixed signals - my intention was not to hurt anyone at all, and I still have some hangups from a nearly 20 yr. relationship where the guy and I were friends with benefits for all but 6 mos. of it. So not exactly the most healthy thing. I clarified my intentions to him then, and yesterday when he came over. But I also told him I wasn’t opposed to a potential relationship between us in the future, if it happened.

So, yesterday, he came over and we watched a movie. So I sat in a recliner while he sat next to me (he was sitting on the crack with the controls to recline, so pretty close [sectional couch])). I wanted to recline, so trying not to be rude, and not making a big deal, I said he was welcome to share the footrest (how can offering to share a footrest be misinterpreted when he can easily just stretch his legs over? Although he did have to operate the controls). In hindsight I should’ve asked him to move over. He ended up sitting super close and misread the situation because he ended up asking to hold my hand and then wanted to kiss me.

What do I do now?

I felt awful and allowed both, so that was really wrong I couldn’t tell him no. Later last night, I said I was sorry to confuse again and reinforced I want friendship, that I’m brand new to dating and a bit unsure/naive about all this still. We bickered some about past things he’d said that I needed clarity on due to being potential dealbreakers, like he casually mentioned my wanting to wait until marriage to have sex again may be a deal breaker for him, and why if I’m not a virgin? Seemed rude.
