<human>: I will start off by saying my relationship with my sons mother is excellent. We steadily eat meals at each other's homes as a family at least once a week. We both attend his sports games and lessons. We do holiday activities ( most recently pumpkin carving) and we have very similar approaches to how we raise our child.  
 We have been apart for 3 or so years, neither of us has had a SO worth bringing up to the other until I met my girlfriend , we will call her brenda. Brenda is awesome, we have been dating 5 months and its been so smooth and effortless. We fell in love in the first few months and its been the happiest I've been in years. 
 I told my EX 3 months ago about Brenda ( well she found out from her group of friends via social media but I was bound to tell her anyways) and told her that any meeting with our son was a long way off and I would talk with her about it. 
 Fast forward to now, I feel like im living two lives. One is with brenda when I dont have my son with me and the other is with  my son and occasionally time with my EX which is nice. But i miss Brenda and when I have him and I feel like keeping them separate is getting to be silly. 
 Can r/relationships share some experiences with this? Maybe some tips on how to approach this? It's a big deal for me and I want to make sure it is handled properly. 

thanks
