I met this guy at a superbowl party. We exchanged FB info from then on we have been texting back and forth. He lives about 45 mins away from me. So a couple of weeks ago I asked him if he wanted to go to the movies with me. He replied "sure if I'm not busy". He owns his own business so I know that sometimes he is busy but I also know you make time for the things she people guy want. Friday comes and goes no text from him. Then that Saturday he text late at night so I don't respond. Didn't fear from him a whole week after that. This morning he texts me in FB  saying that he got a new phone. Then he text on my phone 📱 engages in conversation with me but starts to respond with one ☝🏾 word answers. So finally I just stopped texting him because I cannot figure him out. He goes out of his way to text me but then doesn't seem interested. The one time we did hang out in person he talked a lot more. Should I keep talking to him or just let him go?
