In a relationship (is a quite personal)

Well in relationships its really important that both people know what the other wants out of the relationship and that that's compatible. It sounds like what he wants is a bit self contradictory. You work and support him financially? Then shouldn't he be the one doing things around the home and looking after the kids? Of course I freely accept maybe he'd rather it wasn't that way. Maybe he wishes he got a reasonably well paid job tomorrow so you could quit and he could support you? If so you need to ask yourself will that job of his ever come and if it did would you want to be a mostly stay at home wife? (assuming that's what he wants) Could he live with you being the bread winner and that being a semi permanent arrangement? If so maybe that's an option. Maybe he could be the stay at home dad? You need to have a talk about what you both want.

The same with the sex. You know it's very hard to maintain a health romantic relationship if each party has a radically different idea of what they want sexually. Maybe there is a reason your sex drive is so low? Unresolved emotional issues maybe, a medical condition? Maybe his sex drive is so hyperactive it's a clinical issue (very unlikely unless it's negatively effecting his ability to function). This may need to be part of a wider discussion about both of your issues around sex. But if you can't come to an understanding it could sabotage your relationship in the long run.

So in short "communication, communication, communication that's what you need."

We have tried talking. He works I work I have a Monday to Friday job and he has Wednesdays and Sundays off. However I get tired of hearing all I do is sit in an office all day. Yes it’s my job but I do find my own job difficult it’s not my fault he won’t leave retail. He won’t take a leap of faith. I did and found a different job. The kids stay with their mum 7 nights a week. We just have them during the day. We have spoken about it he’s a bigger person so he’s quite heavy and I have back issues witch make different positions uncomfortable for me and it the whole ordeal causes me a lot of pain  but all he says is go and see a dr. I came off the pill for a while and he wouldn’t wrap it but I don’t want to risk pregnancy right now and he said ill Pull out or we can go down that route if it happens but I’m not willing to do that.
