new guy

I just went on a first date with this guy last night. It was amazing. He treated me like such a lady and aftwrwards, he kept telling me how beautiful I looked and wanted to see me again. However this morning he posted a picture on Instagram dedicated to his grandmother saying "i wish u were here especially through a hard time like this" and dont think that i am selfish you guys its just that i have a feeling he just got out of a long term relationship and might be missing his ex and idk what to do. Please help. I really dont want to be hurt and this guy is a totally sweetheart.
