Dating dilemma...

So I started dating a really great guy. We met through mutual friends, seven months after my marriage ended. We went on dates twice a week, and we waited for a month before we did the deed. We've been seeing each other for nearly two months so still early days...He does and says all the right things, makes plans for next time he sees me, takes me for lunch before he works a shift so it's not all about sex. He seems really into me, and I don't say that lightly. He has a sixteen year old daughter who does not have good health. So here's my dilemma..

I saw him on Friday and he'd arranged to see me the next day even though he had his daughter that day. As it happened, he couldn't see me as his daughter didn't have friends round as originally planned, which is totally fine. When he messaged me he sounded a bit down in the dumps, so I decided to wait a few hours and send him a saucy pic. I'm lying on my bed and have my hair all messed up with a breast in the shot saying 'I'm lying here thinking of you' it's a tasteful pic, not trashy or a pussy shot. BUT..I haven't heard from him since I sent it!! 🙈. I sent it at around 4.30 yesterday and still nothing! What should I do! I know it was stupid and I wish I hadn't sent it now. I'm a bit worried to say the least...help!
