I don't understand him! please help?

I was hanging out with an old guy friend ( no longer friend’s) and we had sex. Only reason why I had sex with him was because I was curious and he just wanted it. After that he said that he didn’t want to hang out anymore after tonight, which is fine. Anyway I was fine up till after ward we finished, he decided to smoke a cig and tell me about how I should get a boyfriend. (note: I never really wanted to be in any kind of committed relationship so there for wasn’t really looking for a boyfriend) He told me I need to change my hair color, change my style to show off my boobs, and I need to learn to talk more to guys. It hurt when he said all of those things. But I told him I already did talk to guys and that I did have guy friends. He then said “well those are just friends.” I then told him “well I’m not interested in committed relationship.” So he preceded to give me a lecture on and on at how bad it is to live with no committed relationship. Now this is the part were I felt mixed up because it made no since. Here is a guy that doesn’t want any commitment but is telling me to go into a committed relationship? I don’t understand and I’m so confused. Does anyone understand what a guy means by saying this?
