pull on

“Since you married her you have to pull on your life with her.”
Is this sentence correct?
I mean “you have to pull on your life with her” as
“you have to somehow adjust & live together with her.”.
Is the meaning correct?

No, that sentence is not understandable in English. We don’t have an expression like that.

As J(K) says, ‘pull on’ doesn’t work here, but there are alternatives…

since you married her, you have to ‘get on with’ her. - ‘get on with’ = be amicable with

or better would be, "since you married her you have to make it work.’ - it = the marriage/the life together.
