<human>: Reasons that have made me worry:

1.  I have not once seen him hang out with friends that weren't parents of my friends.
2. He joined a church and became religious a couple years ago, but I still haven't seen him hang out with anyone outside of church activities.
3. His dating life is nonexistent as every woman he shows interest in has some flaw or another(according to him) that keeps him from going further.
4. My sister(21f) and I are college students, so we can't really be there to keep him busy anymore.
5. Also he had to move back with his mother after the divorce. I'm thinking living with ones mother for 7 years in your middle age can't be great for your self-esteem.

How can I help him develop a social life(or even start dating again)? All he has are us, the dogs, church, and work. He gets incredibly irritable if we aren't around enough.

I should also mention that I really have been a terrible son. We were never too close, as I mostly viewed him as an annoyance most of my life. After this first year of college though, I can see how hard he's worked for me and my sister, and I want him to have fun for once.

Give me the gist of the text in a nutshell
<bot>: Divorced father has no close friends, no dating life, and I want him to enjoy his life without us children.
