Relationships are difficult you find those that are compatible and some that aren't idk what is going on but whatever it is if it can't be worked out then maybe its a sign.
Tactical hit it right on the head. If your relationships are all difficult or end badly then you owe it to yourself to take a hard look at your own decision making process to see whether you need to make some changes in yourself.
the amount of work required to make a relationship work is amazing but well worth it. i have struggled at times but 27 years to the same Man proves to me that it is doable and really worth the effort.
