Hello NooNoo :) and welcome.
Single parenting is a tough but, doable job ime. I've brought up both my children alone; my Ds will be 20 this summer and I spent from my pregnancy without support and Dd is 11; her father would never commit and as it turned out was living a double life.
Ds's father has had no input into my son's upbringing; I was more torn about this as he grew older but, his father didn't get in touch more than once by text and certainly did not help financially in any way at all! But, I didn't expect him to if I'm honest, he was a selfish man - probably still is...Ds got in touch with him about 18 months ago. He can see what an arse he is for himself and doesn't bother much with him. Ds is a strong individual with good manners and a strong sense of justice. He is loving and never fails to tell me he loves me regardless of who else is listening or around. I think he appreciates me as his parent even though we did go through a bad patch which I think every teen goes through. I take full credit for bringing him up. He's not perfect but, he's not a bad lad.
Dd's father does make a contribution each month and this allows her to do activities each week. He lives/works abroad - and long may he stay there. He has made numerous promises to Dd to phone and he lets her down 99% of the time; she just likes the gifts he gives her when he does. I just see it as buying her affection. She never really wants to talk to him but, I do wonder if she's just hiding her disappointment. I'm always there for her even if we do argue a lot of the time.
I love my children and I do my best for them. I wouldn't really care if neither father contacted them again and I don't stop the contact if they do (not that I can now with Ds) but, it doesn't fill me with joy.
