Leaving DH with no support

[androphobic]

DH and I don't have a terrible marriage. It's okay for the most part but I have to make a lot of concessions to him and I've been thinking for a while that I want to leave, I want to feel like I'm truly living my own life but one of the things that keeps me with him is that I literally have no one else. My parents have passed, no DC, we are NC with his family, I don't speak much to my sibling apart from token Christmas/birthday/occasional text messages. I have one casual friend from Uni who I meet once every few months but we don't really talk in between. I have colleagues who are nice but we're just polite not friends.

I've always struggled to make friends, and I don't feel like I would want another partner again. I've never really been single before so I don't know what it will be like.

Has anyone left a relationship under similar circumstances, and how did you find it?

Handholding until someone wiser comes along, op.

OP - what are you asking exactly?

When I read your post, first thing I thought was - that it must be hard to feel so alone. It does appear that you don’t really have meaningful human connections except for your H.
Are you sure you want to leave for the right reasons? Have you tried exploring your feelings / mental state with a professional?
Because what you seem to be wanting to do seems to me as a path to near total isolation and it doesn’t seem healthy.

As a side note - have you tried fixing the parts of the relationship that cause you this much resentment? Why do you have to make those concessions? What would happen if you didn’t? Or at least if you expressed how it makes you feel?

Not the same as he left me but I’m on my own with 4 children and no help with them (father is absent , I have family but they don’t do child care) it’s hard but you cope because you have to, I’m assuming he will still have contact with the children so you will get a break then?

@TurnUpTurnip, op says she doesn't have any kids.

OP, I would agree with PP about seeking some counselling for yourself.
Can I ask what you find difficult about connecting with people?
I am socially quite isolated but I do have family to speak to so I do understand to a certain extent.
How old are you?

@Frigginintheriggin I'm 35. I'm not sure exactly what I find so difficult, but I've always been the same really. It's gotten a bit worse as I've gotten older, but I think that might be down to it being harder to make friends when you're older anyway.

@MMmomDD I'm not sure what I'm asking really. I have recently started seeing a counsellor and she seems really good and I feel like it's helping me. She said she wants to work on building me back up first before I make any decisions but I think about it all the time. I'm not sure how to put it in words. Everything is okay, from the outside we look like we have a fairly nice life I think. It's just so... I don't know. Suffocating? But I do worry about completely isolating myself, I feel isolated now and a big problem is loneliness. If I lost the one person I can speak to about anything as well... I don't know if I'm just thinking the grass will be greener. But it's a big gamble.

It’s great you have a therapist. And I do hope you give it time to work with her.
It is very likely you may be transferring all your issues onto this one thing in your life that you can control - staying or leaving.
And it’s also possible that leaving won’t solve whatever underlying issues are actually there.
You need to invest time into figuring out what actually is going on and what can make you happy - what sort of life can make you happy. And from there - plan on how to get there.
