Yes to expand a bit, my youngest two daughters are from my current relationship. The oldest two are from my previous marriage, but we haven't seen hide nor hair of him since 2007 and although he pays his support as the court has told him too he is NOT an active part in the girls lives.
My husband stepped in when they were around 4 & 2 (now 9 & 7 respectively).
I would say as far as martial strife goes, we've pretty much handled a bit of everything. I don't know if the age difference plays apart in our sex life, but I imagine it does. We've never seen it as an issue, when we are on we are fantastic together and the age never matters a bit!
On to the problems:
* My mother and father massively overcompensate for my older two daughters biological father. It creates a lot of tension for us.
* I am JUST now learning what MY core issues are and fixing them truly, instead of faking my way through. I had/have a codependency issue. From a multitude of things ranging from being adopted, to having an over critical adoptive mother with massive self esteem issues to my first marriage and it's infidelities.
*Money is always tight. Restate that my husband hates his job. He has worked for the same manufacturing company for 20 years. He is an intelligent man, and does much of the companies machine mechanics, he however makes little money.
* In the time we have been dating & then married he has suffered two injuries which resulted in some chronic pain (some of which he still is fighting with now). He had the end of his left ring finger crushed by another mechanic at work (this was before we were married). Then last year he suffered two herniated disks in his back, after almost a year his back is better but not 100%. I know this has again, added to his avoidance of sex.
It's not even all about avoidance, it's the lack of intimacy when something does go on. It's very much like in the book, it's mechanical and just filling a duty. He barely touches me at all.
