What to do?

Sarah
I met a guy and went too far with him on the first date. He said he "loved me" since the first day we started talking but I didn't judge him. Long story short he didn't want commitment, I tried to leave him and then he promised to ask me out. We slept together and he didn't. Even there he was texting girls and hiding it. He didn't text me for so long and he was online in other places, and so on. We were completely not alike. He's a military guy, and I'm a sweet geek. I didn't beg him since we weren't dating anyways so I started texting a guy that I knew that liked me and we are going slow and good. Today he texted me saying: "Sorry I've been too busy". I said "yeah". He said: "I am". And then he said "I love you" and I said: "I don't know what I feel about you". He just read it. I'm pretty sure he is drunk or he wants sex or his bitches haven't text him. I don't want to let him come back to me but I'm scared to talk to him. I'm thinking about blocking him everywhere but that's not mature and I don't know if he'll fight me if I leave him. Also, I feel wonderful with the one guy that likes me and he doesn't deserve me to leave him for a guy that clearly doesn't care. How can I leave him? 😣
