I need Your advice

To be honest I’m terrified of losing him....

I have dated a lot of guys and I seeing that no ones worth it .... but my husband was different... he cheated before on me.... was talking to my cousin behind my back (was my best friend/ sister) but he swore to me there was nothing between them... he even swore on his mom’s life.... when I found out; we were not in the same country.... I was with my family and he was with his back home.... the girl lives near me... so he didn’t sleep with her but I can’t get the fact that he was talking to her on the phone when we were engaged.... it kills me.... I trusted her so much.... and what kills me more is that when I asked for the conversation between him and her... he didn’t send it straight away.... hours later i received them.... I read them... they seemed normal... but why did he take a long time to send them?.... and the thing that shocked me more is when he arrived here I saw his phone..... he changed his phone... even his SIM card..... I don’t know why... he sold his old phone... and got a new one before he came to the country .... maybe to start new? Or like he said. His old phone was old,damaged and needed to replace it..... but that was years ago....

What do you guys think? Was there nothing between them? If so why did not even one of them tell me they were talking? Or am I being crazy.... this story was years ago but me and her don’t talk no more at all... I don’t even say hi to her even if she’s in front of me.... and I never stepped in her parents house after what happened... but I say hi to her family when I see them...

What do you guys think? Did I get played? Why did she do that?

I really need your advice as I am pregnant and next year will be a mother... I wanna forget all this that happened but I can’t.... it’s so hard... it still hurts when I remember it and I cry..... I am happy right now in my married but what happened always stays with me and I wanna start new ..... but how can I forgive and forget?
