<human>: I've been with my gf for about 4.5 years. When I met her, she was interested in the ROTC, but eventually lost interest. We went on dating for about 3.5 years and things were good with some rocky moments at parts. We have a lot in common, pretty similar opinions and left-leaning political backgrounds, we have fun together very easily, and we love eachother. 

In the past year, she has become very serious about becoming a police officer. I support her in this, but we've gotten in some fights about what we think about police violence in this country and some other of the negative aspects of the field. She feels that  I'm not supporting her if I'm critical of certain police actions or policies. The fights we've had have gotten worse, and IMO, her political opinions have shifted further right in the past year. I am also now very aware now of how attracted she is to men in uniform (police and military). I'm just a student at the moment, and I guess I just feel very insecure about how she may think I haven't done a brave or honorable thing like some of the men she's attracted to. Coupled with this, she is becoming further and further involved with groups that typically have conservative mindsets. I just feel that it has become very hard for us to relate to each other anymore. This is the weakest our relationship has been, and I almost feel that maybe we aren't right for each other.

That being said, I still love her, and losing our close connection would definitely break my heart. 

I feel like such a jerk for attaching any sort of negative connotation to the career she so badly wants, but I'm having a hard time ignoring these differences in opinions that we have about things. 

Am i being completely unreasonable? Are these differences something that can be worked through? What can I do to feel less insecure?

Summarize the given text in a few sentences.
<bot>: Gf and I have a serious wedge in the relationship based on political opinions, and I feel completely insecure about her attraction to men in uniform compared to my relative accomplishments as a student
