So me and my gf have been dating for a little below 5 months and I love her dearly. She's supportive, caring, affectionate, pretty much everything I'd want in a girlfriend. 

We were having a discussion about her future with her company and it might have her relocate her job to an area that's around 1 1/2 hrs commute from me which is pretty far if she takes the job. She currently lives ~ 20 minutes away and we've had a little bumpy but eventually straightened relationship. I told her that there are a lot of things she could do such as her relocate to a place that's not so far from her, etc. but one of the things I mentioned is that long distance might not be the best thing for us. I really do like her and I want to stay grounded here but I know I come across as blunt sometimes and I don't know if this is something that I should have brought up.

She thought I was joking but I was serious, since we're only less than 5 months into the relationship. She got immediately upset and mad and said that "I don't love her enough to consider a LDR" and "How could I even say something like that". I went to end the conversation by saying "I love you" and she responded with "Apparently not". 

So reddit, am I the asshole here? Is there something I'm missing
