When people take more than they give to you it is because they feel like you owe them something. Do you? Conflict resolution needed? Are you brave and courageous? After getting your emotions in check, can you have a meaningful, respectful conversation to clear things up? If they mean anything at all to you, begin with peace in mind. Sure, it's uncomfortable! And deep down in your heart you know it's worth it. The goal is to receive clarification to make a sound decision about your connection. Either way, if both parties are willing to move around in your hearts vs standing flat footed on what you think, you could end up better than where you began!
