Guy's Behavior

I miss him, what should I do?

So the beginning of last month I met a guy. He was a bit older than I am and at first, I thought it was a little weird seeing that we had a nine-year age gap. He is a college student like I am. The way he approached me felt so different. He then asked if we could hang out that next day and I agreed and exchanged numbers. We started hanging out more and more and texting and within the first week he asked if I could be his girlfriend. I told him that getting to know more of him, I would say yes. That was a little strange for me seeing that we just meet. One of the things I noticed and kept note of is when I would catch him lying he would get defensive also if I called him out on something he would say "Wait I did? ohh". One of the major things he did was lie about his first time noticing me. We started talking more often a more red flags started appearing, like talking about "our children" way too quickly even though we had just met! Comparing me to his mother in every single thing, dissing his exes, etc that I completely ignored. This is where things get rocky. We were supposed to meet one day and he completely bailed on me because it was "raining" even though the rain had stopped. I accepted it. Something didn't feel right however and I knew something was up. So I decided to call him and he picked up. As we were talking, I heard a female voice in the background and he muted it for a while... I didn't mention it because I was in total shock the whole time we were talking. He said he was gonna call me back. He called me back a few hours later and I picked up. He was talking on the phone and I didn't answer him at all. After the silence, I asked him about his day (at first that's what he talked about as soon as I picked up the phone) and he got defensive once again. I mentioned the female voice and he made it seem like I was hearing stuff. Overall, it's really hard to get over Him, what should I do?
