So about a year and a half ago, I moved to a new town to get an apartment with my best friend. A bit of background, my friend (let’s call him Phil) and I met in our first year of high school and have been really close since then. 

In our High school years Phil began to date a  girl at our school (let’s call her Mandy). Phil and Mandy were always very private and didn’t seem to have much interest in anyone else when they were around each other and while I felt that I was very close to Phil, I really knew next to nothing about Mandy. 

So after we graduated I left the state for school and Phil began at a state university, we still Skype and play video games and I hang out with him whenever I’m home on break.

 After my sophomore year I decided I missed my home state and my friends and I begin to make plans to transfer to Phil’s school. After we’ve moved in together it’s great, but I still feel awkward around Mandy. 

In the time that we’ve now lived together I feel like it’s become more of an underlying issue. Mandy lives about two and half hours away and Phil texts and Skyped with her daily and drives to see her every other weekend (I have no problems with this, he’s got his own life)  Now What has started to get under my skin is that when Mandy is over at our apartment, I feel like we’re back in high school and I’m not even there. I absolutely think they deserve their privacy and I don’t feel like I need to be a part of what they are doing but I hoped that maybe we could be over the high school bullshit and that after all these years they can’t manage to make the effort to acknowledge my existence really stings.
 Phil will now try to invite me along if they are going out to eat but I’ve started declining after we did that and Mandy didn’t say anything the whole time and I felt that I spoiled the mood. 

Over this past Valentine’s Day Phil proposed while visiting Mandy, something he’d told me he’s been planning on doing for some time. Phil has talked to me about being his best man and while the idea of being there for him is something that’s important to me, the idea of being at a wedding where I probably won’t be acknowledged by half the couple sounds like hell. AITA?
