you will heal. yes, it will take longer than if you did not see or hear from him, but it will happen, slowly, but surely.
it was nearly 2 months after my ex broke up with me before i could move out. i realized now, the healing process did begin, but it really got into full swing after i moved out. but in that time i spent so much time analyzing this & that, that it was struggle not to go in the next room and confront him (i did twice, but i do not regret it - he needed to see me in pain at least once after the break-up). although it's been 3 months since he broke it off, i feel like i really have only had one month of healing. i talked to him today for the first time since August 28th.
while living together, i tried as much low contact as possible, but that was nearly impossible. also, we work at the same place, so i would run into him on the train or on the bus or at the cafeteria. so what i did was try to avoid him whenever and where ever i could. i go to one of the other cafeterias (even now, where i feel good), i get in the bus one stop before the "usual" stop and sit in the front cause i know he always gets in the back. i do whatever i can to avoid him, but if i see him, i do not ignore him. i will flash a quick smile or head nod, then turn away. while getting on the train, i used to purposely look to the floor and not look around. i still do some of these things, but it gets better.
since you see your ex weekly, mentally prepare yourself. tell yourself it will be okay before you see him. take extra time to get to rehearsal, add an extra walk around the block. syke (sp?) yourself up. healing might take longer, but you will heal. i cannot believe i am saying this - 10 weeks ago i was dying. today i feel good.
