Is it LDR strain or is it the relationship?

I’m having a hard time telling the difference between fights caused by doing LDR vs. fights that are caused my underlying relationship issues. Does anyone know what I mean? They told me the distance would make things hard. I just don’t know if it’s distance or if it’s us anymore?

How can you tell?

We have 3 months left of LDR, should I stick it out and see who we are when we’re not so far apart? Remembering how we were before LDR is getting harder now 😥

Can anyone out there relate?
