boyfriend vs clingy

Hey girls. 
I don't know if any of you out there experience this too but please comment suggestions! I'm open for all.
I've been in a relationship with this guys for nearly 18 months...
He has never really be the one to organise when we see each other, and if we do see Each other he only likes meeting at home.. 
He tends to choose to game over me which gets me abit ansty..
He also never sticks to plans 
Eg.  Tomorrow night we had dinner plans and he gave me 2 excuses to get out of it and the last excuse was to make me feel bad.. 
I feel like we're drifting and I don't know if that's just me being clingy..
