Background: Exh - kids' father - is classic useless father. Left at 1 year old (caught him playing away, again, and was tired of being the doormat. Couldn't stick to privately agreed visitation and maintenance, so went via CMS. Who are useless. Cue years of non-payments, months when no contact made, huge arrears, feckless behaviour when they stayed with him etc etc. He has moved house, blocked me on everything (as has on-off fiancee), and now CMS tell me that he isn't working (his FB profile viewed via others suggests otherwise!) and that no income (self employed) reported to HMRC. They were in process of allegedly doing big things like removing driving licence, but have now said that because he has moved and they have no address, and he isn't on council tax/utilities anywhere, that they are essentially closing the case. That I'm to tell them if I hear anything. Hopeless. Exh has form for alcohol misuse, DV, etc. A real winner all round. He saw the kids Christmas 2020. Hasn't seen or spoken to or even texted them since. Ignored Christmas, birthdays, move to secondary school, the works. Has kept same phone though - which is the point.
Well, now to the issue. Kids are now (just - 13) old enough to access Whatsapp. And one of them went looking and found him as phone hasn't altered. Lots of "how wonderful to hear from you, love you, miss you". She, bless her, showed me.
I am fucking furious. How dare the arsehole ignore her for 2 years (he had her number, my number, address, landline, email address) and then come the "i miss you"??!! He owes her (sort of via me as I paid for eveything) over 8K in arrears, and two years of her life. I know that whether she has a relationship with him is her choice (sibling has already said not sure they can be bothered as he clearly isn't).
I will not foster a relationship (ie do the leg work/mental load) but will not hamper either. However, I do think I need to set her up with some important self esteem lessons - ie setting boundaries in relationships, and expectations, which is relevant to relationship with bf or with her father.
AIBU in explaining to her both the contact and maintenance issues as being relevant to level of his interest/care towards her, or do I leave that out?
