Jealous & I feel bad πŸ˜’πŸ˜’

So my boyfriend of almost 2 years (January 9th) just recently found out he has a one year old son from a previous fuck buddy. We have lived with each other but are not right now. (I'm in AZ & he's in NV) My boyfriend got a DNA test done. He got the results a week or so later & told me the baby was his.
Β I don't want to say I was hurt because it's not like he cheated on me but I just didn't like the idea of him having a baby with any girl other than meπŸ˜’Β 
But on with the story, so after he first said the baby was his & finally got my reaction he continued with "oh no he isn't mine I just wanted to see how you would react". We then apologized to each other and continue on with our relationship normally..Β 
A month or so later we are planning to see each other & he hits me with " I can't lie to you anymore" I asked him what he was talking about and he says "The baby is mine and I have custody"Β 
This whole situation tore me apart because he lied to me & because having a baby so unexpected pop up is kinda hard to cope with. I know it's not the baby's fault but I'm a little jealous. I'm not going to have as much attention or alone time with my boyfriend anymore I may sound selfish but it's just how I feel. I just recently visited them and the trip was good ☺️ I'm so in love with this man & want to be with him & I mean how can you not love that face πŸ‘ΆπŸ½πŸ˜ but I'm scared of what the outcome may be πŸ˜•Β
