and you are losing interest in your girlfriend/wife? I mean it takes few months up to one year, then its slow decline.
Good thread.
Some have already posted that no relationships stays exciting and fun forever. That's just life , regardless of who you are with.
Sex and resort vacations are fun and it's easy to enjoy each other during those times.
The key is to find real joy in doing the simple things together.
For example, I love relaxing beside my wife, watching some goofy movie or interesting documentary.
I got along great with all my wives. Boredom or lack of fun wasn't what caused my divorces.
a) The first 2 wives changed their minds and wanted kids, a few years into the marriage.
I didn't change and never wanted kids. No way to compromise on that so we got divorced.
b) the 3rd one just wanted to screw around and wasn't happy with an "open marriage", so we divorced.
From MY experience and observations, the real "kiss of death" for a married man is when she changes and wants "something else".
It could be having kids or starting new projects with you directly involved, etc.
Some things a man can go along with and others like having kids isn't.
