I need impartial advice, I am shaking with anger and I feel sick. I hope my post doesn't come out too garbled.
In a nutshell: my dad is having an affair. I knew that there had been an affair a few years ago, but thought it had ended, and I didn't get involved (I thought it was posssible my mum actually knew and that she had decided to stay with my dad, as from the outside their relationship seemed better than it had been).
There is rather a long story leading up to me posting today, so I'll do my best. 2.5 years ago my sister approached me having discovered our dad was messaging and meeting up with an old friend of his. No doubt that it was an affair. She found out when she used the family computer (she is mid-twenties living back home with mum and dad) and facebook messenger was left logged in and literally open in front of her. She looked through lots of messages having seen blatant evidence, and felt awful for having 'snooped', but she couldn't un-see things by this point. By the time DSis spoke to me, it was evident that my dad had told this OW that he did not want to continue seeing her, but I think they parted amicably - they go way back and have mutual friends. Messages were exchanged and there was no mention of any more meetings after this, although with hindsight, I see that maintaining any form of contact and the fact that the affair wasn't exposed (?) was a recipe for disaster.
When I found out about all of this, I was, without exaggeration, devastated. I was so angry on behalf of my mum, I felt like everything was built on lies and that I'd never really known my dad. I shut down and kept this all to myself, I didn't even tell my husband. DH obviously knew something was very wrong, and he may have put 2 and 2 together I don't know, but he respected that I felt I couldn't talk about it. I spoke to him about all of this at a much (much, as in only a few months ago) later dateand I resent the fact that my dad's appalling behaviour impacted on my own relationship like this.
Anyway, I have now discovered that my dad and OW seem to have picked up where they left off. I found out when I used my dad's ipad and saw that he was messaging OW again. And I didn't intend to 'snoop', my dad is not private with his ipad, I had intended to google something on it. He's not even fucking discreet! Urghhh!
I just feel a bit lost right now. WWYD?
