My SO and I have been dating for a little over a year now and it's been the best relationship I've been in..in the very beginning I had trust issues mainly from my last relationship but partly also because he still had girls calling him asking to hang out..but eventually he got rid of the girls but my doubts were still there..now we're engaged and it feels like my doubts got worse..we don't check each other's phones because we have trust in each other but I just can't help all these doubts I have..have any of you ladies had the same thing??
