Cat colony Rehoming?

I wouldn’t normally look to Reddit but there we are. I adopted a male cat about a year ago to be a companion for our female cat. He is about 2 now, up to date on vaccines, fixed, heathy, all that. I can share photos upon request. He’s orange

I got him from a shelter a year ago as a companion for our older female cat. It’s hasn’t gone well. He is super friendly and playful and she in turn attacks and hisses at him. It’s not his fault. He is obsessed with her. So that is why I am looking for a new situation for him.

The thing is, he is not very people friendly. I would consider him semi feral. He will take treats from my hands but I can’t touch him or pet him. Even after a year. I think the shelter we got him from lied to us about his previous interactions with humans.

For those reasons, I think he would make an amazing barn cat or colony cat. He has that hunting skill to be able to survive on his own I’ve seen it. I just don’t know how to go about finding the resources for those. Do those kinds of resources even exist? I have emailed pretty much every cat shelter/rescue in the city and have been met with silence for over a month now. My female cats stress is getting worse and worse and she has taken from hiding under the bed most of the day because she simply does not want to interact with him.

If anyone knows of any resources that might help (not just shelter numbers, I’ve tried) or would be willing to give him a new home, understanding his personality as I’ve laid it out, I would greatly appreciate it.
