I'll give you some background info.
DP was with his DD mother for five years and they have a 3 year old DD. They both made the decision to break up just before Xmas last year.
We've been in a proper relationship for 5 months, I'm yet to meet DD but he does want me to. We've discussed moving in together in the New Year, he stays at mine every night except Wednesday and Fridays when he has DD. He's wonderful, everything I could ask for. Except the fact they're in constant contact and argue a lot! She's asked that I meet her before DD - fine, I'll do that. His ex, knows about us, knows he has a girlfriend but knows basic info but has made a few digs about him moving on but seems to have really gone crazy this last week.
A few weeks ago she messaged him when we were in bed one morning, saying "can DD FaceTime you in a minute". DP really panicked and said "don't say anything, be quiet please!" And "oh no, she's going to see your headboard!" After the FaceTime I sternly said I will not be a secret and I will not be told to be quiet in my own home! He apologised and reassured me I'm not a secret.
Thursday night was my works Xmas do and DP came along, he spent the majority of the time on the phone arguing with her! She'd said she was telling DD he was dead and other vile things. I just keep out of it.
She called this morning, he went into my kitchen and spoke to her. He came back and said she'd asked where he was and he replied why? What does it matter? And then carried on the conversation regarding contact over Xmas.
Why wouldn't he tell her he was with me? I did say to him why wouldn't you just tell her? And he replied well she knows anyway she's just being awkward.
What would you do? I know I'm not a secret but I still feel like he feels awkward. The constant messaging, the arguments, him not telling her who I am (she wouldn't know me anyway)
