Search Results: not want to get back together

I'm 40, and recently broke up with my boyfriend (47) of 11 months. We had hundreds of days filled with highs, he is social, charming, has a lot of friends, loves going out, having fun. He was very sweet, romantic and caring during these times. There were red flags that I tried to rationalize- binge drinking multiple times a week, crippling debt from student loans and cc (>200K), no career motivation and health issues that started popping up (probably from drinking). We had 6-7 arguments over the last year, that I thought were heated but never out of control (and always under the influence of alcohol). The next day we'd both apologize and move on. I realized he'd get overwhelmed then, and sometimes even at the smallest disagreement or when I needed to vent (when both were sober). I showed concern about his health and debt and the stupid fights that happened while drinking. Asked him to cut back, but he was super defensive and in denial. Fast forward to the new year, we were going to move in together and he was going to propose. He suddenly started acting disinterested and cold and last week suddenly declares he doesn't want to move in together. I'm taken aback and ask why, and he brings up the fights and that it's too frequent. I ask if he's overwhelmed with all his issues, and he admits he is, but keeps blaming me for the fights. I say I'll work on being more understanding and only bring up stuff while we're both sober and in a calm way, but I can't change the past, only do better in the future. He's reluctant to accept my words and I finally ask in frustration if he wants to break up. He says he doesn't know what wants, but needs time on his own to think. Over the next 3 weeks, I don't hear from him and he ignores my call and texts, forcing me to text and email him an official breakup note. Rationally, I know he's not good for me in his current state, but my heart still loves him. I want to know if a man like this can change. Does he deserve a second chance?
