Re: My husband has no friends
Some people just don't want/need a ton of friends. I have a very small, select group of friends, and I'm happy that way. Others might think I need more, but I'm happy with what I have. Each of my friends meets a certain need in my life, or more than one, and we all get along and have a history, together and individually. I make new friends when I meet someone that I feel strongly that I'd like to be friends with, but I don't go out looking for a new friend to do *this* with me. Maybe he's like that.
On the other hand, if he's making you feel pressured to be everything to him, that's a problem. While I strongly believe your romantic partner should be your best friend, and be ABLE to meet all of your needs, I don't feel they should HAVE to meet all of your needs. I think they need to be able to, so that in a situation where another friend might not be able or willing to help, your partner can, but they should not have to meet all of your needs all of the time, as that can be draining. I hope that makes sense there.
Have you sat down with him and talked to him about all of this? Not just a "I wish you had more friends" talk, but a real "I feel like I need to be everything to you, and it's hard on me" kind of talk. Maybe he doesn't even realize he's doing that to you. And sometimes we misinterpret our partner's behavior and put pressure on ourselves that they never intended us to feel. A good, air-clearing conversation could be all you need to change this. Getting it out there may make him pay more attention to his behavior and stop making you feel pressured, if that's what he's doing. And if it's just a misunderstanding on your end, he can clarify that and you can get some of that weight off of you.
And if...you have that conversation and it turns out he knows what he's doing, and does expect you to be everything, or you get him to see what he's doing but he refuses to change, maybe just stop trying to be everything. Be what you can be. Be a wife, be a partner, do what you feel you NEED to do as that role in his life, and refuse to feel that pressure to be everything. Maybe that will force him to find new friends to meet those needs that you aren't.
