I doubt that anyone would be questioning whether a woman had been in an abusive relationship meaning she had to drop friends..
OP, a lot of projection on this thread. Personally I had a similar situation except there were no romantic feelings. A long-standing friend got married and suddenly, out of nowhere I stopped hearing from him. At all. I was more baffled by it because although we weren’t in each other’s pockets we had fairly frequent contact and then nothing.
I put it down to the fact he was newly married and probably busy. But then around three years later I heard from him that he was getting divorced. We met up again and it transpired that she had been abusive. I can’t go into detail because it’s potentially outing but there were even suspicions that she may have tampered with medication he was on etc. He has a long-term illness, and she claimed it was so bad he was incapable of doing anything. When friends rang they were told he wasn’t able to come to the phone because he was too tired, when actually he had no idea anyone had even called. While married to her he had no energy or stamina and once he got divorced everything changed for him on that score.
She always picks her men. Always men with a bit of cash- not loaded but enough that she can skim off for herself, and with something wrong with them. The one she moved on to after him had cancer.

Anyway that was about fifteen years ago and we have remained in touch ever since - in fact he is one of my closest friends although there never has been any inclination towards anything more.
The only thing I would say here is to guard your heart. Some friendships are not worth rocking the boat over. And if you have previously been such good friends and he has thought of you as being the one to contact, then it’s possible that friendship is realistically all that is on the agenda, because if a romance goes wrong then the friendship is usually lost.
In the past I’ve had friends who I had feelings for, but the friendship was too important to me to ever explore those. So do ask yourself whether only friendship will be enough and if not whether you should be opening yourself up to potentially getting hurt if that’s all he sees.
