Ok people.. I'm sorry.. it's another advice thread.. but I need your help..

Story: My X-GF have been/were together for just over a year. We've been living together for almost 8 months. Just last month, we broke a lease to move into her parent's basement suite because she plans on going back to school in this August and, as a couple, we needed to save some cash for that. Well.. we just broke up. We were arguing a lot as of late.. a lot of stress was put on the relationship from outside sources and this tension was too much to bear. So I broke up with her.. she turns on the waterworks .. then.. the idiot I am.. I take her back.. you know the whole "we'll make it work.. we just have to try.. relationships take effort.. compromises.. blah blah".. yeah.. so.. because she has such a strong personality.. she was waiting for me to become vulnerable again.. so now she basically broke up with me.. well.. i think im fine with it.. i wasn't for a while.. but i think i am now.. it's been 8 days.. the worst 8 days of my life.. but anyways.. on to the advice asking.. i will be moving out, hopefully, by the end of the month.. 3.5 weeks left. The friendship relationship is going downhill fast.. we're both bitter at eachother.. what advice could you guys give me to make the next 3.5 weeks not such a living hell. The only think i've realized is to try and be civil.. don't intentionally irritate her.. and DON'T plead for her back! No matter what though.. she is still the biggest bitch to me.. this morning.. i said "Good Morning".. she didn't even look at me.. grrr.. How do I/we do this without ruining what could be a great friendship?

Thanks in advance people.. appreciate it.
