Relationship Decision

I’ve been divorced for 2 years now. I had managed to get out of an abusive relationship but it took me 24 years. I’ve been seeking to know myself better which started by dropping out of my strict catholic upbringing. I started seeing a therapist, started dancing again, and now my body is more strengthened through my yoga practice. I still have feelings of inadequacy which brings me to my question. I seemed to have attracted a man into my life who I found a great energy with. I was later disappointed to find out he was 11 years younger than me. I just turned 50 and I feel fantastic and people say I look much younger. I’m so ashamed of my age, and I tend to attract younger men in my life. I continue to see this man who has a young child and is a single parent. He sometimes pokes fun regarding our age differences, but always says that he is attracted by it. I feel anxious about this. This person also has issues with maintaining his body in shape, and is constantly counting calories, and intensely working out. It makes me feel less than when I see I’m not as “tone” as I would like to be. This person also relaxes by smoking cannabis, and claims it helps him function better. Can this be? Now I’m faced with being in a phase in my life where I need to make a decision on what this journey is with him. I truly enjoy his company, but then it takes so much to maintain myself, because I scared about my aging, and I think it would be easier just to call it quits. How do I handle this relationship?
