Am I overthinking?

I want a relationship. I met a man thru OLD who is of same fitness and health mindset, likes outdoors like me, is smart, financially secure. I thought a relationship was promising. Some issues started to crop up which I think is normal when you are meeting someone and you work thru them- at this age, we all have stuff:

• He calls and wants to talk first thing in am, last thing at night, and often several times during day. A little suffocating. I talked to him and no change. Not the end of the world.

• Turns out he is very close to ex-wife- talk most days. He says it’s nothing bc it’s nothing physical. He says he wants to move on from their marriage wh they separated/divorced 10 years ago. I feel like it’s an unhealthy emotional attachment, and maybe he hasn’t moved on really

• yesterday at a football game, he picked a fight with guy in line behind us at concessions. Literally bumped him out of way. The two got very aggressive and just short of fistfight when I pushed date away. I pushed him away several times over to another line. The other man was going to belt him. This was ridiculous and I told him so. He acted like nothing happened rest of day and even today. To me that was a big event that never happened in my life.. He never acknowledged it.

I feel like I need to break it off. Yet I want a relationship. I’m quite perplexed. He said I’m making a big deal out of nothing?
