Why is he still texting?

I met this guy online a few months ago and we started texting right away. He is a much bigger texter than I am and would text me every day several times. He came on very strong which was a red flag to me since he’d just gotten out of a year-long relationship, but he was really sweet and funny so I let it go. We texted about anything and everything. We met and went on several dates. Most of them were initiated by him. We slept together after the third date and continued to hook up after the next several dates. I saw him about once a week for the first several weeks. However, things really started to fizzle after about six weeks or so. He still texted me almost every day but the texts were very matter-of-factly. He also hasn’t made an effort to hang out with me in a couple of weeks. I just assumed he wasn’t that interested and decided to let it go. Yet he still texts me every few days. I’m aware that some guys like to keep girls on the hook and I thought this might be what he was trying to do but the text conversations we have aren’t the type that would keep a girl on the hook. Our earlier texts were much more flirty and the conversations went on forever. Now he’ll just ask a question or make a statement, we exchange a few texts each, and the conversation is over. For example, he recently texted to let me know that he started his new job. I said I was excited for him and asked how it went. He responded that it went well and asked how my day was going. I then responded that my day was going great. After a couple more similar exchanges the conversation ended. Several days later he texts me on a Saturday evening asking if I’m having a nice weekend. Again, the conversations are all very short and matter-of-factly and he does not make an effort to hang out. I should also note that I do not initiate any conversations with him. I did when we were texting and seeing each other regularly but I stopped when he cooled off.

In addition, around the time he started cooling off we had a couple of awkward texting conversations about “us” during which he said that he was just enjoying himself and not thinking too hard about things, but that he enjoyed hanging out with me as I make him happy, laugh, and he feels like he can be himself around me. He said he was just enjoying the way things are and thought we were on the same page. I said I had no idea what page that was and I interpreted this again as he’s just not that interested and would just like to keep up the status quo rather than move forward. I believe that he’s seeing other women as we were never exclusive. I decided to write him off and move on. I didn’t confront him I just stopped initiating contact. I only respond politely to his texts and usually after a delay. I really liked this guy and was disappointed when things cooled off and would like to know why, without any effort from me, he’s still texting every few days to say absolutely nothing. If he’s not making an effort to hang out, isn’t trying to hook up, and isn’t trying to keep a conversation going then what’s the point? Why text at all?
