tbh I'm a bit torn on this one.
On the one hand I agree that if you're happy as things are currently then why end a decent relationship.
But on the other hand if there really is no future then it is far better to discuss that while you’re still at the beginning stages than to fall deeply in love and to then realise there is no future and to get far more hurt than you would otherwise.
But you need to decide what your limits are e.g. can you really not see each other weekends/holidays until such times as one of you can move? Even if that is in years to come? Is never seeing or speaking to each other ever again really preferable to a few years of living a long distance relationship?
I agree that it’s not as simple as say, moving halfway etc esp if you both have children and 50/50 contact and so on. But equally you are in a new relationship and there really is no absolute rush to be together right now. Yes perhaps you would like to get married again in the future and have more children, but there are no guarantees in life.
LDR’s aren’t for everyone, and I disagree with those that say two hours is no distance at all – it is when you have no way of moving to be together and if you don’t see each other regularly, and perhaps that is the key, how often do you see each other?
Fwiw I am in a not dissimilar situation in that I am in a relationship with someone who is three hours away from me and currently neither of us is in a position to move to be together because I have a ds who has 50/50 between me and my ex so no possibility of me moving, and he has a job which he has been in for the past twenty years and which is in a specialist field so not easy to just find another one. We have talked about him finding a job down here and that is not something which we have discounted, but in the current climate it certainly shouldn’t be about him finding the first job he can just so he can be with me – job stability is important too and we certainly don’t want to be together living on the dole

At some point he will hopefully find work here but I am not pressuring him into anything like that because when moving the situation needs to be right and that includes the job especially if moving from a settled, stable, long-term job into a new one...
We could decide the situation is hopeless and decide that we should split, but why on earth would we – I make him happy and he makes me happy, we spend every weekend together and when he has holiday etc, and worst case scenario my ds will leave school in seven years time....
I’m not about to throw away a good relationship with a lovely man for the sake of some romantic ideal of lost togetherness...
