<human>: Give me a shortened version of the text

So i have been with her for 4.5 years so far.  For the first couple years everything  were all fun and dandy we would go out and see movies, go out for dinner and so on and so forth. We did things that we both enjoyed most of the time and enjoyed each others company.

However since about 2 years ago when I joined the military things have been going downhill. We have been fighting a lot more and recently it seems to be about 1 in 2 conversations end up in an argument  of some sort or we get mad at each other for slmething the other said. We always 'make up' but I feel like it gets a little bit worse every single time. When we spend time together we seem to get tired of each other after a few hours.

Those things we used to do rarely happen anymore as when we spend time together we tend to just sit around watch a TV show, maybe talk a bit, or have sex. We never seem to be able to agree on what to do, most of the time we can't even come up with anything to do.

Both of us recognize that there is a problem in our relationship but neither of us wants it to end at the same time. We have decided that In a few months if it doesn't get any better or if it gets worse we are going to end it.

The issue I'm having is that despite this I feel like we don't really connect anymore since we are both interested in such vastly different things.

 I'm not sure if we should even bother waiting to see if it gets better or just end it. I don't want to give her a hope that things will work out and then just end it but I also don't want to break her heart. 

I just need some advice on what to do here, as I can't figure out on my own what the right choice is.
<bot>: Gf and I have been arguing and fighting a lot more. We dont really do anything together anymore. We both recognize that there is a problem but neither of us wants to end it. Any advice?
