Hey, hard it is. My mind says you need to cut the relationship if you want more, but neither one of you is prepared to truly sacrifice, which of course can also lead to resentment. Your heart of course tells you something else. Thing is whichever way you turn it is a sacrifice.
I am in LDR. We love each other, that is very clear, but the problem is more to do with uncertainty of future owing to previous relationships (ie divorces) that have not turned out to be the 'forever' that one was hoping for, this is transferred into the newer relationship, and because of the distance stays ever present.
The hope of the 'traditional' family unit is gone, but we have to understand that there are many 'normals'.
For now, my doh and I have our own businesses that require us to live in separate locations, we have children at primary school, his he cares for on a 50;50 split with his ex, and therefore him moving is not an option either, just for now. Ultimately we don't know how our relationship will develop, but we do talk of future, we make holiday plans, we talk about when retire, we talk long term, and really short term, never mid-term, because mid-term is not achievable right now.
So for the moment, we skype EVERY night, we are the last person we speak to, and we remind each other that we love each, and RESPECT each other every day...when that stops it will be time to re-evaluate the relationship, until that time...(It's hard somedays though - that unfortunately is just life regardless of LDR or not)
