<human>: Give me the gist of the text in a nutshell

So my dad ditched when I was only a few months old, and moved three provinces away (NS to Ontario), and hooked up with an older woman who already had 4 kids. He visited every once and a while until I was about 7, then disappeared. When I was 13 I needed his signature to get my passport and my mother had to go through quite a bit to find him. Finally when we did, I agreed to try to keep a relationship with him. I'm 19 now and still talk to him, maybe once ever two weeks over text and once a month (if that) on the phone. He doesn't try to keep a relationship- all he wants to do is give me money to try to win me back. He doesn't text me for anything other than to say he's trying to get a job to give me money. So far, it's been 4 months since he originally promised to help me with my university costs, and still nothing. Every new call or text is just "I'm trying to get you money, love you." 

I want a relationship with him but I don't want to have to go chasing him to be part of my life. My mother is now married to a wonderful man who has been more of a father to me than I could have ever asked for and I love him for it. But then there's bio-dad. deadbeat, no job, strange wife, 4 step kids over the age of 25... It's strange.

I don't really know what to ask in terms of advice... Should I confront him about it? Should I try harder to contact him (I text him every once and a while but it always ends up the same way - "I'll get you your money soon)? Or should I just let it run its course and wait for him to disappear again?

Thanks reddit.
<bot>: dad is a deadbeat, Father's Day is bringing up emotions from me, I don't know whether or not I should really try to keep this relationship going.
