Husband wants to connect with BIL and I didn't agree

I'm about to sound a little toxic here lol. But I keep me and my husband's circle married people only. Single people tend to be upset with their own boring single life so they try to ruin happily married people's lives. My siblings are married. All my husband's brothers are married except the last and he's my husband's HALF brother. His dad had a bastard on his mom when he cheated. My husband has never been super close with him because his mom wouldn't let him since she was upset at his dad. I am a sympathetic person. His brother has been through a lot. His mom and step dad and other adults in his life ruined him and put him through a lot of trauma. It's why he joined the military at 17. His 8 year contract just not too long ago and he started crashing out on tiktok making weird tiktoks saying things like losing my virginity at 26. And also shit talking the military and how his recruiter lied to him and manipulated him into signing an 8 year contract and talking about his terrible experience in the military. So part of my husband's family on his mom's side has been calling him a communist which is extreme. Buy he's online acting like an 18-20 year old who'd experiencing life for the first time. He's in his mid 20s! Going out and drinking. Talking about sex with different girls and his possitblity of experimenting with his sexuality. According to him he lost his virginity like 5 seconds ago so why do all this. He's just crashing out on tiktok then messaged my husband saying he's coming to town and he knows they've never been close but he would like to me so my husband is wanting to build a relationship with his youngest brother. We don't hang around none married people for a reason and he's living the life style of a very single guy. I think my husband should wait until his brother settles down..I expressed these free 3 separate times and he said he's still going to try to have a relationship with him when he doesn't have to. He's a half brother that his dad had outside of wedlock that he never grew up with. I'm irritated that my feelings don't matter.

@Nadia I do trust my husband. I'm just not ignorant like most of the women on this app and understand temptations 🤣. I keep them out of marriage and his brother is a temptation
