I'm 16, and I've had three dads. The first, my biological dad, left my biological mum when I was three and I was adopted out (I haven't seen him in over 10 years). My adopted dad wasn't very interested in my life, like he was there, but we never had a real father-daughter relationship, like my older two sisters (his natural born daughters). He died less than a month before I turned 11. And the last, is not actually my dad. He's my brother in law, but he's old enough to be my dad. I think of him as dad, talk to him as if he was my dad, tell him my problems, guy stuggles, school stuggles, everyday life problems, etc., and I love him like he's my real dad. 

Is that weird? Is it weird that I think of him more like the father I never had than the other two who were legally my dad? I feel kind of bad, but they weren't there when I needed them, but my brother in law was, when I needed somebody the most. (Stopped me from suicide) I don't trust easy, and he's the only person I talk to/get advice from/trust 100%. 

I just want to know if that is all weird. And if it's wrong to have a different 'father figure' in my life... 

Thoughts?
