I was dating someone for 8 months - there was always a gut feeling that I was not 'exclusive'. Things went quiet for 2 months and I saw photos of him and his new partner on social media - which was a horrid way to find out.
He has sent a message to let me know he has met someone else but loves my company and wants to still see me as a friend and my daughter when he has his daughter. I don't think I can do this as I still have feelings for him, I feel he made a fool of me and was deceitful and dishonest. I ended up sending a message saying it would not be fair on his new partner as he should spend time with her and her children building on their relationship and memories.
