I think it will be easier in some ways but harder in others. The plus will be you won't have to look at him on a daily basis and be reminded of all that is happening in your M, but the bad part is he'll be gone and you'll eventually miss him. But...this will be the perfect time to rediscover who you are as a person. This is a good thing.
I agree with DG totally. It kind of cuts both ways. It's nice to be free of the drama, but you will miss him. Be sure to really work on GAL'ing.
