bf relapsed and took the commitment off of us

Hi- I'm new here and posted to my blog but let's see if this works for advice. My bf of 3 mos, who's an amazing, talented and kind man is an recovered alcoholic and I didn't know it. Maybe the fact that he only drank soda was my red flag. He relapsed during our courtship and I stayed by his side when he got sober again (took 5 days). I support him completely and once went to AA with him. I'm a love addict or codependent on men I'm with. If he was falling down drunk- I would leave him but that's not the case. Since sobriety is primary- he took the bf/gf title off stating that he can't offer me a major commitment right now. I understand that. Some like to judge quickly and say he's using me and that's not his intent. He knows I could leave if I wanted to and he can't say anything about it. I told him I may see others too while he's working on himself. I fell in love with him easier than others. He doesn't love me (so he says). Me being a love addict , I felt hurt and abandoned once again. However, the relationship has not changed other than the title. We see each other like always and talk/text. Even planning a short cruise in the future. We both agreed that we never want to be out of each others lives (even if we stopped dating). This came from him (and he is not contolling at all). Almost seems like he does love me but too scared to say it due to the relapse. I am better now emotionally now but wasn't a few weeks ago. So here's the kicker - or the question- part of me feels that I should focus on another man (FWB only) so my love addict heart can be guarded from my love interest. That may be detrimental to my mental health altogether. I want to just play it by ear with my guy but scared of getting hurt. I'm not sure what is best and no I will not leave my guy but since he's wrapped up a lot with A A and just life, I can focus on others and yes- support for me - on here because I obviously need it!! Are there any posters here that are like me that fear losing a sig other so badly that you obsess over it and try doing more destructive things? Advice is welcomed and sorry so long!
