I feel stupid.

My husband and I had a fight and I haven't heard from him in a month I'm pregnant with our second our first is one years old. It was his birthday yesterday so I thought to break the ice even though he was in the wrong I'll try call him and he didn't answer so later I sent him a seductive photo and said 'birthday sex?' He read it but didn't reply or call or come. Yes I sent a photo but this man isn't just a ex bf kinda thing it's my husband whom we have children together. I'm starting to think maybe his talking to someone else and I'm devastated I feel so stupid for sending that photo now and decided to stop trying to contact him. I don't know what to do ladies please I'm just hurt
