Dating

Why hasn’t this guy text me back?

I started talking to him online last year, I was pregnant and single during the time and we found each other on a dating app. He kept asking me for a date but I was unsure. We stopped speaking Summer last year. I randomly heard from him again 3 weeks ago after not speaking for a year and he asked if I was still single and to give him a chance and I agreed to go on a date with him, although I was reluctant as he is only 22 and I am nearly 28. I never have dated a guy this young before. Anyway to cut a long story short, we met in person on the 30th July and we had sex in his car and passionately kissed, I was insanely attracted to him. He filmed us having sex as he told me he was a virgin and wanted to film
his “first time”. We texted back and forth quite a lot and I asked him if he just wanted me for sex and his reply was “No, I want something with you, I have been wanting you for so long, I want to see how things go and if we don’t work out I want us to be friends” he seemed to really like me, he said he couldn’t be happier, can’t wait to see me again bla bla but…he hasn’t been texting me for days. I have been texting him, he has been reading my messages but not replying. I haven’t heard off him in nearly a week. I asked him please to answer me and tell me if he wants to see me again and he hasn’t answered me. :( I am really confused and lost. I want answers and he isn’t giving me them. Please guys, help me out! Help me understand the male mind. Is he not interested? Has he maybe found someone else? He is Indian British and I am White English. He is Muslim and I am Christian.
