I don't really know where to start but here goes..... I've just found out I've been lied to for months and I'm in shock. My fiancé ( we've been together a long time) is really good friends with a work colleauge who started last year. I was very suspicious of this lady as I knew they got on but I went through a really bad patch last year where I convinced myself they were having an affair. He strongly denied this and said they just got on, that was it!!
She ended being posted somewhere else and I was led to believe that they hadn't been in contact, just at this point friend on Facebook. So I started feeling alot happier in myself, we'd not long had a baby when she started working with him and things were good, we had a good Xmas etc. I still asked a few questions about her but all I got was ' I'm not sure, I haven't spoken to her since last year'. I think deep down I knew this wasn't true, I just couldn't prove it.
Anyway, details I won't go into but I've found out they have been in contact the whole time, haven't met up but speak on the phone quite regular. I was absolutely furious. He swears to me she's just a friend, feels sorry for her ( she's been having a shit time) and doesn't fancy her in the slightest , they just get on. We chatted and I seemed ok with it just upset he had lied to me but after a pretty sleepless night this morning I'm so upset. I feel like he is having an affair, I can't handle the lies and I thought I was the only one he confided in, not someone else. I seriously don't know how I feel. I just feel numb, can we get through this??
He's told me he won't end the friendship, I've just got to accept it 
He also wants us to meet, I don't know what to do??
