horriblethisis---think: short-term pain for long term gain. Sometimes, this is also refered to as "delayed gratification".
It is significant is human development---the ability to tolerate discomfort for a short time to gain a reward (of some kind), later.
Normally this ability grows as we grow from young children into mature adults---with a good self esteem.
Perhaps your self esteem is the issue here.......?
Really...how good is this relationship?? You recognize that you are "lying to yourself" by minimizing what you know is a big red flag for future heartbreak. But, are you also l lying to HIM..... Is he aware of what you think about this?....have you told him exactly what you are thinking? In a solid intimate relationship---you should be able to share this with your partner. After all, you are willing to share it with strangers--but not him
Solid relationships are built on honesty and trust at the base.
Just a few thoughts for you to think about.....
