I don't know if I want to be married...

I love my husband. We have been together since we were 15 and now been married for almost 5 years and have two kids. He has been the only guy I have ever gone out with or anything and vice versa for him. But for the last while I just feel like a sibling or a roommate. It doesn't matter how many times out of the house without the kids we get, at the end of the day I still feel lonely. He doesn't want to have sex like ever. He hasn't made me orgasm, or been interested in making me orgasm since before we got married and after a while I just stopped initiating things because I just felt used for his pleasure and that's it. But now it's been a month and he hasn't made a single move. Not a kiss, back rub, even a hug. I've asked him to go to counseling but he won't go. I don't know what to do can any of you give me any ideas?
