Boyfriend - no contact = breakup

For context: Got into a relationship with a 48 year old man (I’m 38 year old woman) after we had been dating on and off since June 2021 to January 2022. He asked me in January if I wanted a relationship with him and I said yes. Things hit off very well. Communication and togetherness was even better than when we were dating. I was in the clouds. Then suddenly the excuses poured in. He’s busy, he’s tired, he has a woman stalking him etc. Then one week of no contact turned into 2.5 weeks of no contact and I had ENOUGH! So I texted …no response. I decided to pay him a visit at his home. He was there AND so was another car. But who’s car? Could this be another woman? I don’t know, maybe, possibly,I don’t know. Instincts says yes my mind says no. He has older kids 19 and 24….family….friends….so Who knows? So I called him while I waited in my car. No answer. I instantly grew heart broken. I became so sad. Lost of happiness lost of appetite loss of sleep. I texted him that I don’t think things are going to work. That I loved him and for him to take care of his self. Then drove off and cried every night since. Some days I eat some days I don’t. I’ve lost 10 lbs already. He hasn’t reached out to me at all. Today makes a total of 3 weeks. I don’t want him back. It just hurts so much that someone I cared about and that I loved did not have the decency to respect me enough to say the relationship is not what I can handle at moment. I expected more of him than what he gave. It’s baffling considering he’s pushing 50 and is still an immature coward. Pray for my swift break up recovery.
