In going to focus on your current position.
Would you like to live with a partner?
Would you like to be married?
Would you like to have a family?
If so, you've been in this on off relationship, (the latest on for 6 years) since you were about 18. It's been off & on, you're not cohabiting, you haven't gotten engaged, you haven't gotten married, you've not had any kids ... You e now discovered he's been cheating on you.
It hadn't really gone anywhere, it hasn't progressed, you've now found out he cheats on you.
Are you getting what you want out of this relationship with this man??
You are 35.
Your fertility is hitting the gradual but speeding up slope towards infertility now. Most women are ok til 39, but the ease of getting pregnant and the pregnancy sticking etc is reducing. By 42, some women are infertile. By 45, most.
This man sounds like some kind of sociopath or narcissist. You're wondering why he doesn't care m/isn't showing you he cares while you "starving, crying" etc but you've already told us he has no empathy and seems to act very risky and disrespectfully and cavalierly towards his friends, fanily and even clients whose money is his income.
You don't have the time to analyse him.
You don't have the time to fuck around if you want a marriage a family etc with a better person.
You don't have any more time to waste if you want a family.
Get out and meet other men, after reading those books.
Don't put all your eggs in one basket with that sociopath ...... He's certainly not putting all his eggs in one basket, is he now??!!
Your life turn out very differently if you get off his hook and go and have fun, meet people, and try to meet another partner.
