Hi there,
Sorry for what you're enduring... many of us who come to these boards are obviously going through tough times, else why would we be posting on boards seeking support and answers?
Many of us can offer empathy for your situation, but that doesn't necessarily help you in the topic of your post.
In answer to your question... Should you go get yourself slapped?
Ummm, it seems like you're having a very difficult time in a situation of tremendous stress, unimaginable disappointment (time and time again), and seeming minimal hope. For you NOT to feel overwhelmed would be a sign of a disturbed and disconnected individual.
Feeling overwhelmed merely makes you a normal human. Having thoughts of how much more peaceful your life would be if you simply quit trying-- again, you're normal.
I echo what the others say about staying focused on your daughter. You're a grown man who can comprehend what is going on. She is a tyke who doesn't understand it and who has no ability to advocate for her best interests.
I also suggest that you find a way to feel empowered in this process. Surrendering to the mother (or making some statement of such) only encourages her to continue her campaign. Refusing to give her emotional satisfaction, and instead only using your attorney to enforce your rights and advocate for the same will give you a sense of control, will help you feel "above" her crap, and will be the best tactic possible (if possible) to get the mother to behave.
Also, think of this as a very very long process. Every daily battle is yet a tiny little skirmish in the eventual outcome. Keep your eye on the goal.
If you don't have a goal, then identify it and put it in writing. E.g., "I will have 50% custodial time with my child, and I will share in raising her."
Once you have that goal, and you're faced with the latest minor conflict, respond to the conflict in a way that best supports your goal (rather than just having a myopic solution to "win" the tiny conflict of the day).
Having your big goal, and building momentum to that goal, will help you weather the daily challenges. Without that big goal, every passing day feels more hopeless.
I don't know the details of your situation. My ex caused so much conflict between us for nearly three years. I had moments like what you describe within yourself. We're ending up our custody evaluations now, and we're heading into our custody trial in coming weeks.
The tremendous gift that comes out of the h*ll that you're describing is what I'm now appreciating-- I stayed on the high road for 3 years and documented all that my ex did. As a result, I'm a shining example of a devoted, cooperative parent as we end our evaluations and enter trial. My ex is a shining example of an uncooperative, vindictive, poisonous, irresponsible mother. The cost was huge, but the gift that her poor behavior delivered is invaluable now.
Stay focused on your girl. It'll all work out in the plan that God intends. Part of staying focused on your little girl means taking care of yourself (no more heart attacks!) during this very stressful process so that she has a dad while she grows up. And, having dad locked away in a padded room isn't much help either, so continue to find support (e.g., these kinds of boards, friends, family) to keep you going strong and with increasing confidence!
Best wishes for you,
DD
