<human>: Can you succinctly summarize the text in 1-3 sentences?

Some background info: My boyfriend and I have been together for a year, 6 months out of that was long distance but now we are back together in the same place, we have never broken up during the time we were together and we are very serious about each other.

My boyfriend has made a new female friend (I will call her Cindy) 1 or 2 months ago when we were still long distance. They are both in some volleyball team/program and they see each other quite frequently. During the whole time that we have been together, he has never gone out to dinner with a girl one on one but he did with Cindy which of course made me jealous and we had a big fight about whether I trust him or not. The reason this situation made me suspicious was because he told me last minute and he made it look like there were other people coming but then he eventually told me there was a very high possibility it will be just him and Cindy, whatever that means. He ended up cancelling on her due to our fight and then he went out to eat with her (just the two of them) at a semi-fancy restaurant a few days after. They only ate dinner and they went separate ways and that night he came home and we skyped and things were fine. I believed that I was overreacting and I am just insecure however there are two things that still bother me:

1. He said she has a boyfriend but I found out through her instagram that she is single (she always makes posts about single life)
2. Few days ago I was sitting beside him and he deleted all of his texts from her and he thought I didn't see but I did. I immediately confronted him and he said this is just something he has always done, he deletes texts that are idle. I don't really understand because the last text that was sent was from her and he was the one not responding, not her
<bot>: My boyfriend deleted texts from a girl I was once suspicious about, am I overreacting or is he possibly cheating?
