I Don't Know What to Do

Ok. I was thinking about Sean a lot yesterday. I even looked at his wedding pictures, blah blah blah, etc etc etc. Now, I get on facebook and he's invited me to go to his baby shower/diaper party/paint our baby's room! thing. I really just don't know what to do. Should I go? Should I not go? Should I say I have to work and that we'll have to hang out another time? My mind was blown from Doctor Who, but this has my mind in a knot. I'll probably ask Mary for advice. I don't see how Sean could even want me there considering I haven't talked to him since May, no April, maybe March? I really don't remember. I need to pray about it.
