got turned on and left high and dry

Ugh so my SO came in and started foreplay with me and just as we started getting into it he stops just stops I said what happen he says he needs to shower then comes out of the shower and starts to get dressed like no I'm not laying in our bed waiting for you (and still waiting) why why would he do this to me. Guess I'm going to bed sexually frustrated. I'll just go get our 10 month old daughter and cuddle with her since he went to the neighbors house. Ugh
