Name frustration...

So I need to vent and I feel like no one understands and maybe it is just my hormones ...brief synopsis of situation ...my boyfriend has his two boys full time who he had with his ex...well now we are pregnant with my first ...we aren't married (yet) and not sure when that is happening . His family has a tradition of two middle names.  Now...here's to the part where I'm frustrated. The baby is going to get his last name (which  is the type of name that can be given as someone's first name) then the baby is going to have two middle name which I thin is a bit much but fine it's family tradition.  So since we aren't married I think he should get to pick one middle name and the baby gets his last name ...and since it is my first child I think I should get to pick the first name and one middle name.  He hates the names I've picked out and I dislike the names he's picked out ...so I even went as far as to compromise and say well then none of the first names either one of us picked out will be used and we will have to find a name that both of us like.  But that isn't working and I'm getting frustrated because I want to have a baby name by the shower and it's just being swept under the rug.  Idk sorry for rant.  I just feel like this is supposed to be something fun and exciting and every conversation we have in regards to baby fails to find a resolution.
