<human>: Can you succinctly summarize the text in 1-3 sentences?

I met my good friend M last year when we hit it off when he called in for help (I work in IT). I worked the following weekend and he called me on both shifts and we spoke (both times) for over 6-7 hours (of my 12 hour shift). We went on a date to formally introduce ourselves and after a few dates he said he wasn't quite ready to date since he had just gotten out of a relationship but wanted to be friends. A few months later (April/May) he went back to his ex and I was supportive of him (i.e. "If that will make you happy then go for it!"). They were on/off and I remained friends with him and we became closer. A few months ago, he and his ex finally called it quits for good and we hang out regularly. We fooled around last week and since then he told me that he wasn't comfortable doing that since (for whatever reason) he felt guilty and that he felt like he was doing something wrong (even though he is single). I want him to take the time he needs and even if after he has taken that time, he doesn't want to fool around, I'm okay with that. I realized, after talking to a friend that I am (or am in the process) of falling in love with him. I know these feelings aren't reciprocated and I also don't want to lose him as a friend because I value his friendship. Please help.
<bot>: I'm falling in love with my close friend who isn't mentally ready for a relationship. How do I stop my feelings from further developing without hurting our friendship?
