<human>: Summarize the given text in a few sentences.

I (f,23) have been with my bf(m,23) almost a year. Everything has been great the whole time, we've both been very happy, he is always saying sweet things to me. We have met each other's families and talked about plans for the future.

Lately, he has just been acting strange and seems to not want to talk to me or see me as much as usual. I honestly have no idea why, it was kind of an overnight change. I've asked if things are ok and he said yes, but I know something isn't right. And I keep getting worse and worse feelings about it. And this seems like a petty thing to worry about but weirds me out, he deleted two pictures of me off of his instagram..just those and none others.
<bot>: Basically seeking reassurance or advice from anyone who thought for sure their SO was about to end things with them, were you right and how did you handle it?
