He doesn't text me anymore?

[Jasmine]

Ok so me and this boy have known each other since we were 6 because both of our mom's went to school together and are best friends but moved down to Cornwall when the son was 2 (I live in Birmingham so it's quite far away) but since we were 6 my family have gone down to Cornwall to stay with them every other summer. We've always been really close and I've always had a secret crush on him. This new years we went down to Cornwall because they were having a new years eve party, this time when we went down something seemed different between me and this boy (the relationship seemed a lot more flirty) he confessed he had always secretly liked me and on new years eve at midnight he kissed me unexpectedly and for the rest of the week we acted like a couple but never actually said we were in a relationship (I think because we had known each other so long and there was so much history it was weird now we both knew how each other felt and didn't know how to act). Before I went home he kept saying he wouldn't see or do anything with any other girls and I said the same but we still didn't say that we were "boyfriend and girlfriend". For the first week he texted me non-stop and he talked about our future and how he loved me, and we just seemed to be getting closer and closer. But then all of a sudden the conversations seemed to change and were almost awkward, it started to feel like I was the only one putting the effort in and he had just stopped. Then I noticed on his social media page he was having a lot of contact with his ex and and he had liked a photo of her in just her bikini. I know he hangs round with a lot of girls both in and out of school but I never had a problem with that because I trust him. Now I only get a text from him if I text him first and he says he misses me but it feels like somethings changed. It makes me constantly angry and sad but I feel that by texting him when he has stopped texting me I am annoying him because surely if he wanted to speak to me he would wouldn't he? Part of me wants to leave him but then what would I say because I don't even know if we are in an actual relationship? But then I have known him for so long and we have so much history part of me doesn't want to let go.
What should I do?? Any advice would be greatly appreciated as this is pretty much taking over my life now

if he is not testing you, then you should text him back. If he still doesn't text you bakc, he's not interested in you.....nobod wants to read this

Have you ever taken into consideration that HIS mother may not have liked the fact that the two of you felt this way. His parents may be fine with a friendship, but may not condone anything further between the two of you because they do not want to fracture the relationship between the two best friends.

He only has a mom and when she found out about us she came and hugged me and said she was really happy about it and said to her son that he should "stick with me cuz I'm a lovely girl" so I can't see that being the issue

Leave him? You have to be "with" someone to leave them.

Just think of this as a brief thing.

If he is not texting or answering texts - then that is a hint.
