Armachia's advice is pretty much the same as my own. It's up to you to set the boundaries you're comfortable with in your relationship and decide when you feel they've been crossed. Without knowing the specifics of either side of the story, the best I can say is to ask yourself whether it's your own insecurities at play here making you unhappy, or whether you feel you're being mistreated/neglected by your partner. Either way, however, the end result is going to be the same: you need to talk to your SO about it. Let them know how you're feeling and why, and try to find a compromise together.
