Ex got a girlfriend and we haven't seen each other in over a year and he wants to save me for later?

when it is more convenient for him to love me instead of this new girlfriend. I told him how I felt, and he accused me of acting like an asshole and "freaking out." He kept trying to explain why he's getting into a relationship and speaking over me. I told him about my feelings over text and that's when he asked me why I was freaking out on him. He told me he loved me and that I was #1 and not her and says we can't be together now but maybe in the future. He has had 2 girlfriends since we've been away and sleeps with whoever he wants and I don't get jealous when he messes around--only when he'd rather be with someone else. I haven't slept with anyone else in my life or been in a committed relationship since him. He keeps bringing up how he feels when I just mess around with other guys. I didn't let anyone I wanted to sleep with sleep with me because I didn't want to hurt him. He accuses me of messing around with guys and gets jealous and says he is just looking out for me and doesn't want me to get hurt. He's the one who said no long-distance relationship, and we agreed on it. It is really hard for me to concentrate on schoolwork because I'm hurt and I feel betrayed and angry this time. He still acts like he's the only one who has a right to do anything with me, and he won't even pay for my plane ticket. I have been basing my goals around what I want for our future, but I want to **** it all and move on. I still feel like a bad person for wanting to moving on. I want to sleep with whoever I want, but I feel scared and like I'm breaking our promise to each other. This is the 2nd time he's tried to save me for later. He told me I should fly up to see him while his 1st girlfriend was away for the weekend. I feel like crap. I don't know if having sex this early would be bad for me but I am very sexually frustrated and have no confidence. How do I keep my mind off it? When would it be a safe time to give my vagina its rights back?
