I know you know that only you (lot of you's but makes sense right?)can decide when enough is enough. I've found myself on serveral occasions feeling exactly how you are right now but have chose to continue on the DB path for myself, my kids, and also my w.
Is this truly the point where you feel like you are done? If so their will be no judgements from me and I will support you to the fullest. I assume that is the cast for most if not all of us on here. We know what a great person you are and if you feel like your curent sitch can no longer work for you then you make that decision.
But what does that look like for you? What can be your next steps and what are some immediate short term goals?
Lately I have been feeling very saddened thinking of my w and the pain she is going through. Yes this was her choice but something inside of her heart and soul told her that this is what she needed to do at this time to try to find her happiness. It doesn't seem to be working out too well for her right now but its her path and hopefully it will lead her to find her happiness, w/ or w/o me.
It totally sux for us but I am extremely greatful that this has allowed me to find myself and learn a lot about who I am just as you stated above. Even if we D this lessen has been priceless.
