Husband can’t take a hint from his friends and it’s embarrassing

We’ve been married for 11 years and have 4 kids. We have a happy marriage but my husband always talks about needing guy friends which I understand because I’m really close with my friend group.

At my husbands last job he made friends with a guy after they bonded over a shared hobby. The guy invited him over to his house to work on a vehicle so my husband went and had a great time. He would go spot until eventually he was going 6 times a week. I was irritated at the frequency because we have young kids but he told me he was being invited over and the guy needed help so I just let him do his thing. This continued for a couple of months and then I got a Facebook message from the friends wife. She was really nice but said they have young kids etc and my husband is arriving over there everyday uninvited and isn’t picking up on hints that it’s not appropriate to be there. I told him the about the message and even showed it to him. He was mad at me and said I just didn’t want him to have friends but did slow down the frequency for a couple of weeks. He then eventually started again and the friend just stopped answering his calls and stopped answering the door to him when he would show up. They’re no longer friends.

We just moved. My husband has no male friends because of how strong he comes on. The next door neighbor also works in vehicle and they got talking one day while my husband was mowing the lawn. My husband went over there had a great time and I could already tell it was starting again. It’s been two weeks since then and my husband is over there anytime he’s off work and he stays for hours. Every time the neighbor opens his garage my husband is over there without an invite. He has started waiting in our garage with the door open for this man to open his garage and literally sprints there as soon as the door opens. I overheard the guy talking to his wife yesterday while I was in my back yard and he told her not to open the garage because he doesn’t want the “weird neighbor” showing up again. I again told my husband this and he said I’m making it up. Today is his birthday and he’s been in our garage since 9am waiting for the neighbor to open his garage. The neighbor got home from lunch with his family around 1om and my husband went over there as soon as he saw their car pull in. He’s been over there for hours. I don’t know what to do anymore. It’s such a huge ick and it’s incredibly unhelpful to leave me with the kids on my own all the time. I just came over to my moms because i just wanted some adult company. What would you do?
