I've added the link because I know lots of people posted at the time on my thread. I'll give a quick summary and then update.
I discovered my partner of 5 years was having an affair in November last year. I was shocked to say the least and completely at a loss of how to tackle things.
So since then I have gathered lots of evidence to the extent of the affairs and the lies that have been spun. I've discovered he is meeting men for sex as well as continuing the affair. He continues to lie to my face about all of this.
But I have signed a tenancy agreement today and I'm moving into my own place soon. STBX knows nothing about the arrangements yet. I'm planning to tell him tomorrow evening.
I've got almost everything arranged now for the move so I need to start packing. Obviously at this stage he's going to realise something's amiss. I'm really not sure how he will react though which makes me nervous. If I could move out quickly while he was out I would!
