My first post. Feeling so sick. Briefly = been in (what I thought was) a great relationship for nigh-on 4 years. For circa 6 months partner had become noticeably distant, and not just because he works away a great deal of time. He lives with me (my property although he contributes financially and is generous) and has children from a previous marriage that visit every other weekend. I thought everything fine between us until around 4-5 weeks ago when I stumbled on a text message that appeared on his sync'd computer - there was no contact name, just a number with "Hi, is this --? Are you free in (area he was staying at a hotel in) tonight?". He consults for a profession and I help him with his work, it seemed a strange request as consultations are booked in advance and always during daylight hours. I googled the number and the name and was devastated to find that it matched with an "escort" (nice description!) agency. Apologies, tears, first off said it was only for "company" (the website contradicted this in a big way) then he "didn't know why he'd done it" - she apparently never text back....Also found out that he had been planning to move out and rent another place to be closer to his children - despite us planning to move (using my equity) next year. Bit awkward to type properly right now due to the holidays and him being here, but am happy to answer further questions/elaborate but - after I thought we had talked it through I woke becoming suspicious again and asked to see his phone and messages - turns out he has been discussing our relationship with none other than the sister I am (or thought I was) closest to. Hope this relays my feelings, just seeking some independent advice really as now I really don't know where to turn. Thank you
