Hoping my marriage can be saved :(

[Maggie3]

My husband emailed me today about when I wouldn't be home this coming weekend so he could do yard work. He also wished me luck in the marathon I'm running Monday. It's so crazy. Last year at this time he was telling me to pack my suitcase because he was taking me to an island after the marathon, this year he is emailing to "wish me luck, regardless of our situation". He is going to come do yard work Monday- dashing my hopes that he'd show up to cheer me on. I responded pleasantly though, thanking him. We also have a wedding next weekend, a female friend of his who I became close with. We decided I would go, as I'm doing a reading and her and I are closer than they are. The Bride knows everything going on and asked me to bring my best friend instead. I'm nervous for my first big event without him and the questions I'm sure to get. Plus, it being a wedding is bittersweet. I know I will have fun with my friends though.
