I'm not jealous of his daughter. I respect everything you said in your post apart from that. If you read what I have said.... he uses his daughters name to lie to me. I have no negative emotions towards her. It's because he will always always always say its her that he's talking to online at 3am etc. Everytime I'm ignored he says it's her. 3 days ago he said he was not replying to her even though she was asking when they could chat.
3 months ago he faked going over to her house a 45 min train ride away. He asked me for the money for the train. Then he told me his phone was dying and to message her for the address fast! He then said she was currently at an appointment. 3 hours later her boyfriend confirmed that my "partner" hasn't arrived yet.
Another hour passes. He messages me. He's on the train coming home. He's annoyed because she was at the hospital and he couldn't find her house (he's been there before)
The next day his other daughter spoke to me saying he had asked her and her sister for the train fayre. Turns out all 3 of us had paid for the train. He knew about the 10 min appointment and knew her partner would be at the house to let him in.
Also his phone had died yet he messaged me on the train because it turned out a random lady had a charger in her bag for him. The truth is he didn't go to the station. When j saw him that night he was all wide eyed and was clearly on something.
Oh and another story. He called me pathetic on the phone one day infront of this daughter. She then started to tell people I controlled her dad. She then started saying she wanted to spend more time with me. She invited him over one day. He begged me for a food shop. I was sat waiting to hear he'd received it. He ignored me for 6 hours. Said daughter had picked him up with a female friend and invited several of her women friend to her house some nearer my age. To meet him.
I've been disrespected several times by him using this daughter as an excuse.
It's a mess that I've processed. Absolutely he can talk to her all night everyday 24/7 and if it's her he's speaking to I'm happy for him.
But a few weeks back he started following a dating site on Facebook and alot of the posts had numbers for WhatsApp chat.
So maybe he's lying 99% of the time and I'm frustrated that he blocks my defences by saying. I'm talking to my daughter.
I hope this clears it up. It's not a jealousy issue it's me expecting to be respected as a human being.
The rest of your post thank you. Good advice and I will take it
