Ok, long story...

I was fwb with a guy I used to work with for 9 years... In December 2014, we decided to take it to the 'next level'... So we're in a "relationship" of sorts... We're committed to each other, meaning not sleeping with anyone other than each other etc.. He sees a counselor to work through some of his issues and I see my psychiatrist to work through mine... He's 22 years older than me and is divorced. He's been cheated on (as have I) and he has trust and commitment issues.. I have trust issues. Last week we were talking and we got on the topic of my parents and he mentioned something about "dating my fathers' daughter".. Yesterday, I brought it up and asked him about it.. his answer was it's "absolutely 100% true".. so I guess now we're "dating". I asked him if that meant I could update my FB thing to say I'm in a relationship with him.. he's unsure why that's important..

So, I guess my thing is - he says the right things, but does a variant of the opposite sometimes..

He's a recovering alcoholic (13 years sober this year).. stopped smoking around November 2014.. and quit doing drugs the same time he became sober (13 years)..

I am 100% supportive of him in his sobriety and everything he does. How do I show my support to him in all of this while still expressing concern over relapses... I have no previous experience with AA, 12 steps, etc.. what does he do/need to do in order to maintain his sobriety.. (other than the obvious of avoiding drugs, alcohol, cigarettes - and any environment where they may be present)..

He's also working on starting his own business which requires alot of his time (I support his starting a business and respect the amount of time it takes and always ask him if there's anything I can do to help).

We both have the same wants and goals... It just seems like maybe he's embarrassed to be with me (age difference, or my physical appearance), or he doesn't want people to know that we're in a relationship of any sort... He says he has never cheated on anyone and never would (same with me) but sometimes I feel like he doesn't want me to broadcast our relationship because there might be someone else (even if he's not sleeping with her - maybe he has feelings for her...) - he's told me he hasn't gotten over his exes yet, but he wants to continue our relationship.. I dunno, I'm just really confused.. I love him, I want to be with him, I want us to have a family together at some point... But maybe he's just not quite ready for all of that? Why wouldn't he want me to put our relationship on FB?

Any opinions/advice are welcome Thanks for reading the wall of text...
