Not sure where I stand

[RainbowDashstolemyidentity]

I've been with DP for almost 2 years, both have kids & we don't live together. We didn't tell the kids for the first year until we were sure that it was going somewhere.
During the first year it was great, we dated (proper exciting dates) had weekends away & were v loved up.
During this last year since the kids have known the dates have slowed down, we maybe go to the cinema once every couple of weeks sometimes his son comes too & he just seems massively non plussed about us!
As the months go on he seems more distant, stops telling me stuff that he's doing (pretty major stuff like booking a holiday for him & his kids)
Today we had a "firm" arrangement to see each other I text him this morning to see what the plan was, he replied saying he was on his way out for the day I didn't bother replying
He's not the greatest communicator,is quite VERY forgetful and gets wrapped up in his own stuff very easily!
I guess I'm just wondering if I'm flogging a dead horse really.
I want it back to how it was I'm just not sure we can get it back

It sounds like he's a BF rather than a DP really. I suspect that if you let that concept run in practice you will learn more about the reality than if you continue to act as if he was a partner in life. Because he doesn't really sound like he is. It's probably better to re-establish perspective now rather than later after you've expended a lot of energy into what might be a case of mistaken identity - that he is "the one".

Be frugal with your energy output at this time, would be my advice. See how it goes but retain your sense of independence and don't cling to expectations. 2yrs is not that long given there are dc involved too. Just be careful is what I'm saying.

tipsy is spot on, 2 years really isn't that long.

I'd say he's making it pretty obvious where you 'stand' I'd say he's a BF too rather than a P
He's stopped making efforts I'd probably do the same tbh. He sounds nonplussed about making effort.

I hate it when they do this

But yes, sounds like he is not very into you any more. I suggest a tactical withdrawal - if he sharpens up his act after you have ignored him for a few weeks, maybe he was just being lazy. If not then it sounds as though the relationship has run its course.

Thanks for the replies.
You're right re the BF not P bit I guess I just thought more about this relationship than he did
