Be in a relationship just because of our son?

We've recently got back together. On my end, I'm trying to work it out because I want him to have his mommy & daddy (but of course I have love for him)... I grew up without my father, and it messed with me bad. I don't want him to have to go threw that, but then again were starting to argue. Ugh.... We're actually into it at this very moment.. ???
