Of course you feel confused, and confusion makes us feel unsafe. I'm very sorry about that.
It is very hard to not take it personaly, and yet that's what we need to try to do. For my pwBPD birthdays are very scary, and feelings are always scary. And I'd add "we men are stupid" to the equation.

My gf has bought me expensive presents and then hide them and not let me see them, because she felt I wouldn't like them. Then she returns them or loses them. The fear of rejection makes them do unexpected things.
My gf has told me many times she doesn't want anything romantic with me or anyone. She often says "feelings are crap". Then she does those kinds of looks you descrive. Or takes my hand, or asks me to sit closer. They are very insecure, and they fear getting attached to us, and then facing that we will leave them. So it's better not to love. On the other hand, he wouldn't need to do that if he didn't love you a lot.
You need and deserve the certainty of having someone on your team, that will be there when you need him, that would respond and listen to you. Of course you do. And we love people who often can't show that they love us, and sometimes even seem like they don't. It's very tough.
You need more sources of support and help, do you count with people close to you?
