Lets just call this guy Jared.?

I had tried so hard to get back with my ex. He had been my first in the ual department. I don’t know how I became so ‘infatuated’ with him. I thought about him day in day out when we were dating and even when we broke up. But the more I tried to get with him the more he pushed away. We finally came to a conclusion of us dating again. We’ve been dating for about a week now. He’s been giving me gifts which are good I guess. He’s trying to get his life together which had been as problem before for us. I kissed him recently just once and it was weird. Nothing, I felt nothing. It was more of a surprise kiss like oh. But even being with him now I feel awkward or like a friend yet we can talk on the phone. Deep down I know I care about him and the thought of losing him kills me. He recently confided in me in the 3 months we broke up he had with 2 girls, virgins and had oral with one girl. He wanted to tell me so the story wouldn’t get back to me and I would be angry with him. Now I just feel hurt. I understand I was with another man and had relations as such but I cared about that man and we had a monogamous relationship. And now “Jared” says he doesn’t care about those girls it didn’t work out and he cut it off so he date me. But I don’t know I still feel hurt and the sparks still aren’t there. What do I do?
