Would she take me back even though it's been 7yrs since we spoke plus she got 2 kids with her new guy but she has a child with me?

I've been with her just over 3years, we got a baby boy together, but I went to prison.. She got a new guy she's been with him for years also, also they got 2 kids together a house and a dog, we ain't spoke in 7 years our son is in care so I don't have a reason just to go round..
