What to do

Me and my boyfriend of over a year broke up about a week ago due to me having a panic attack and not attending his friends wedding reception. We still live together because we have a house together. I have my own bedroom now. We're both doing our own thing by ourselves and with our friends, and I miss him. It's hard not to cuddle up together every night and kiss him and do things as a couple. I want him to miss me. How do I go about that? I want him to see I'm doing okay without him. I noticed when friends & I went to the bar Wednesday he almosted looked sad that I was getting ready to go out.
