Relationship anxiety

Do any of you ladies deal with occasional anxiety in/about your relationship?

I am an over-thinker! And occasionally this leads to me having terrible anxiety with my boyfriend of a little over a year. Things will be going great, something small will happen and the overthinking begins. Trust me, it isn’t something I can necessarily control, I have tried.

We’ve talked about it and I’ve told him it helps me to just come to him and explain what’s going on in my head.

Last night I did this and he said ‘don’t feel that way’. Which did nothing to reassure me.

Just curious if anyone else maybe has this issue in their relationship and how you and your SO handle it.
