So to start off my advice seeking I need to preface it with my situation. Due to a rough past and not having enough money to fight a lot of nasty lies I lost custody of my son when he was 8 yrs old to my biological mother at the same time she divorced my dad (after 30+ years of marriage). This happened in 2014, I literally had less than $6K to fight her claims and get a roof over my head and so I lost. I do my best to be a good mom even though for majority of these 5 years she has not been a good person to me nor a good influential person to my son who is special needs. We are now on tolerable terms (we can talk and not argue typically, and we both do what we can to make sure my son succeeds-he is the most important person in my life). My problem is this....she knows that I am getting married next year. I want my son to walk me down the aisle (he is 14yrs old) as we asked my dad to marry us.
My son and her live about 5 hrs from where I am getting married. We live ourselves about 3.5 hours away from it (we are in NW LA and the location is Arlington, Tx and my family are all in the Houston, Tx area).
Due to the long history of my relationship with her I am unsure on if I want her to be there but then I don't know how I would get my son to my dad's house so he can bring him up to the wedding.
I also partially don't trust her to keep her word if she says she will come and bring him and then doesn't do it (she has done something similar before when I graduated from college with my AAS with honors-first in my family to get a degree and she wouldn't bring my son to see me graduate-but this was right after she got custody).
What do I do/How do I handle this?
