Yeah...you took yourself off the market and while the guys weren't actively pursuing you they still likely considered you an "option" even if it wasn't a conscious thought.

Most people on reddit disagree with me but I'm a firm believer that truly platonic opposite sex relationships are extremely rare. I think there's a video on your be asking men who are friends with women if they would sleep with their female friends. If I recall correctly most, if not all, said they would. Funny enough most of the women said they wouldn't.

A couple of my friendships were allegedly brotherly, even calling me their sister, but it wasn't true. They apparently wanted to sleep with me but didn't want to say anything since they knew it was unlikely to happen and telling me would ruin the friendship. And they were right because I truly did think of them as brothers and would have stepped back from being close with them. I didn't find any of that out until years later of course.

When I took myself off the market I didn't lose my guy friends but our friendships became much less close and most contact was through my husband who was also part of our friend group. I became closer to my female friends in the group though so that was nice.

I think the change is weirder for you because it happened after marriage. If your husband had lived with you before that I can guarantee it would have happened sooner. Your husband is now a real person to them. Someone they don't want to disrespect. When he was just your LDR boyfriend he was more hypothetical and when they saw you they didn't see him. Now he's real and he's their friend too. They don't want to give him any reason to think he can't trust them and the easiest way to do that is to distance themselves from you.

It sucks but the odds are that even if you talk to them about it, it won't change.
