Tristan you going out to a couple of bars and having a few drinks & dinner by yourself isn't sad, I'm actually pretty damn proud of you for doing that.
And you did the right thing not going to the apartment and helping decorate it, seriously bro, you are doing it, as hard as it is, you are doing the right things. Sometimes you just need some reinforcement & encouragement so here it is, you're doing great and handling this like a champ.
The new outfit thing is a good idea, you need to start doing more of that, losing weight, going to a gym, playing sports, it's all good, all part of that GAL idea, keep it going!
