Should I let my X-Wife torture me daily..?

Yes she hates my guts & has screamed this loudly in public places on more than one occasion. She says my son drives her crazy and wont listen to her, he is only 2, I try to see him but she has decreased my allowed time down to less than 15 hrs (over 3 days) a week. Quit her job in lieu of my child support paid and the fact that her boss is not nice:(. Should I avoid the torture and deal with the torment of not seeing my son or should I fight the powers that be and attempt to regain control in the face of increased adversity?? Please help and email if u want more details. She hung up the phone on me for asking if he went to school were i am supposed to pick him up ..it is a bit snowy so I called to get the needed info to plan my day yet it is a total offense, I offered to take him to a nearby reastraunt and she said noo to icy, total hoax. IS this n.u.t.s or am I the one one needing cracking for dealing with it.. My son and I are very close.. but for how long at this new rate.
