Once again. Just because you cheated doesnt mean you have to cave in on everything he wants.
Fight for your rights as a spouse.
It's interesting looking at this from the opposite perspective. Are you in a no-fault state? Then cheating, especially emotionally doesnt mean squat in court. Sometimes if kids r involved you can spin it.
How long were you married? What is your attorney telling you??
Dont forget it took both of you to get where you were at. Everyone on this site has to take responsibilty for the state of their marriage. Even if the only part they played was marrying/choosing that particular person.
Start standing up for yourself. NO ONE should be allowed to just WALK AWAY from a marriage. Especially if the other person wants to work on it. Unless your dealing with extreme issues suc as abuse, most issues can be worked out in time.
Stop letting him DEFINE YOU. You need to LOVE yourself first before he could. Use this time to WORK on that. Look into CO-DEPENDENCE.
