You certainly had a busy week, i.e., shopping, working and friends coming to visit. I like the fact that you won a grill. What a way to start off a new position! LOL!
I'm glad your GF isn't pressuring you to file. You need someone in your corner that you can talk to about these things, i.e., just as she needs you to be there for her.
I would be a little hesitant allowing him to come into your home for the drums. Even though he said he only wants the drums, you don't know what else his "sticky fingers" may touch and opt to take as well. I think you are on to something by thinking he should come over when you are there. You can always be in another part of the house as he loads his drums up.
Bright, he's got a ways to go and if the drums will make him happy, then so be it.
Enjoy your special day and I hope the work week is a more settled one for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
