The main problem is "she"
She force me to leave my wife but I don't wanna do that, I like my wife very much, I also have a 2 years old daughter.
The problem is I don't do something which my g'frnd wants and she abuses me too much
You sound like a person with an innate sensitivity and that sensitivity is being abused by people who see that as your weakness.
It can be difficult for people with this sensitivity to find where their social strengths are when their minds and emotions are busy picking up signals from others. The trouble is with empathy is that it can have two sides, one side of it useful in 'reading' people but the other side ends up doormatting to what you perceive as what other people may be wanting or needing from you.
What was your upbringing like? Where you discouraged a lot as a child ie., did either one or both of your parents find ways to put you down, like in verbal ways? Verbal discouragements may be interpreted by the developing personality as "you're not good enough" (for eg.). So the person who thinks that 'they are not good enough' will try to prove in subliminal ways that they 'good enough' are somehow.
Thus, a person who has experienced early discouragement conditioning can end up being a doormat for the use of others - and, like I mentioned, others can perceive that as a form of people-pleasing and use that person to their own ends. It does not promote the respect of others, in other words.
I pulled that quote from your post to illustrate this.
What I think is that you are seeking acceptance and approval via a love affair. But I would suggest you to work on the 'weakness' side of the empathy-sensitivity you have and turn it into a strength.
"No one can make you feel inferior without your permission." --Eleanor Roosevelt
Don't give them "permission" - try to cure yourself of cowing to the discouragments and criticisms of others. You sound like a kind-hearted person who does desire the best for others. This is something good about you, but work on how other more hard-hearted people are perceiving that about you and learn to say things like "
no" and "I don't agree with what you're saying" and "that's not any of your business" and "you've judged me wrong" - things like that. You don't need to say these things in a defensive way, just with a steady, quiet manner.
When you can learn to stop the criticisms, nip them in the bud (in the knowlege that your own conscience is clear about your own doings), others will see that you're not going to present yourself as weaker before them. It's a pecking-order thing not merely relegated to the world of the chicken species. Human beings are good at doing that too.
I concur with pixx, look after the emotional well-being of your child, and seek to love yourself in healthy self-respect more.
All the best to you.
