Ok so when me & OH first got together over 3 years ago he was still seeing his ex for a while. She had a boyfriend & he did (me) so they did it a couple of times. When I found out I was heartbroken & ended it but he wanted me back & said he didn't want her etc etc. We managed to work it out as I do love him & I do believe he was in a confused state of mind & really fucked up but he's sorry. Fast forward to now & I am 12 weeks pregnant (we got engaged on Christmas eve 2014). I don't check his phone anymore & haven't for a long time however out of curiousity/slight paranoia I decided to check who he has been searching on FB (I know his FB password) and it turns out he searches for his ex girlfriend once a month regularly. He searched her on boxing day (2 days after we were engaged) & new years day. He hasn't searched her in February once we'd found out about the pregnancy however I am so confused whether hes searching her because he still has feelings for her or because he's curious about what she's up to (her FB is private but we know she is engaged & living with her partner due to mutual friends). What do I do? I feel like I can't tell him I've been invading his privacy but Im just so fed up. I feel like I can't get away from his ex (she also works on the floor below me in the same company) & my confidence is at an all time low as I feel so fat & ugly at the moment... advice please?
