I feel like people don't take my feelings into consideration when they're speaking to me or anything, it stresses me out because there's nothing I can do about it and I don't want to seem like a dick if I confronted them about it, I've had a few relationships have a lack of consideration and do horrible things like cheat, say or do screwed up things, or more complex situations, I'm not certain how I should approach this stuff or how I should fix these issues

I don't have a solution for a lot of my issues and problems but this one's been bugging me for a while now and I don't know how to deal with it or handle it
