How can you (men) be supported through loneliness?

Hi, everyone.

I'm hoping to hear some perspectives on how you may want or need support when dealing with loneliness, specifically guy friendships, if that's okay.

Quick backstory: My husband is a really cool guy, lots of hobbies, very funny, but has a really hard time making new friends. His social circle has dwindled really hard. He has a few close friends but everyone has gotten either really busy with their own lives or has turned out to be really superficial. He's been looking for some more substance from his male relationships for a while.

We're about to have our first child and my husband is realizing that he doesn't really have anyone to lean on. His friends are okay with being supportive but in a kind of dismissive, "you'll be alright" kind of way. It's been hitting him hard and making him feel very alone.

I know I can't make friends for him, or tell him what to do, but Im curious how you guys navigate feeling lonely in your male friendships (if so) and what kind of support might help you during those hard times.

Thanks in advance if anyone reads this and for your opinions and sharing your experiences.
