Aries man=so confusing. .. help

I've been dating my aries man for a little of a year and a half. Bout every three months or so he drifts off. Me being a usual cappy and not understanding what's happening break things off bc I think it's what he wants but doesn't want to be the bad guy. It's always been a quiet split when it does happen. The past two times have really been yucky with him yelling at me, telling me he doesn't love me, doesn't know if he us with me bc I'm sick or not. Just mean. This last time he told me he wanted me to find someone else. The past two times he was extremely intoxicated and another family member was around who us angry all the time and thrives on chaos. Feeling his anger.
I love him and I know he feels the same. When he found out I was sick he broke down and told me that if something happened he didn't know if he could go on.
I am his first real gf ever. He is 35.
Recently he started texting me and kept asking about my dates. Getting mad wanting to know what I was doing. I haven't been anywhere with anyone, but someone is telling him I am. He lives down the road from me. I have to go by his house to come or go. He sits outside till late at night with his best friend drinking. He can see everything I do.
I'm confused as to why he is angry. He told me to move on and had I really been out y should he care.
He wanted to come over and talk. He admitted that he didn't even know what happened. Hell, neither do I really except alcohol and a family member boosting his insecurity and anger.
I haven't heard from him since the other night.
I don't know what to do. I love him and would live to be with him. What does he want and how do I handle this?
aries, any advice?....

Sounds emotionally abusive and emotionally unstable. He depends on liquor for his problems when really all he does is sweep them under the rug with the alcohol and they resurface each time. He also sounds insecure. The childish trait of him is a given, seeing as though Aries are the babies of the zodiac, they hate to be babied, but will throw a fit if they feel ignored, yet they need their space, yet they want you near. You??ll have to find a balance between those things. HOWEVER, first I sense he has issues within himself that neither I nor anyone else on this forum can assist you in helping him with until he realizes he has issues. Good luck on that.

I got the idea impulsv. Lol
He has only told me he doesn't love me when that one person is around trying to find something wrong with us and feeding him more and more alcohol. Any other time he loves me to death.
As far as him looking for another, I don't see it happening. He is always in his yard. During our relationship he never made me feel like there was someone else. I mean, I had access to his phone, computer, whatever if I needed it. I never had a reason to check behind him.
His best friend of 20 years tells me he lives me but that it scares him to death bc a relationship is something he has never had. He agrees with me on this one person causing chaos.
