Welcome to Psych Central, xhndth22x. Sorry you are suffering from disappointments in your relationships. Having unrealistic expectations (for me when I was young I wanted someone that would make me happy all the time) can lead to early termination of relationships. The more one expects to get from a relationship, the deeper the disappointment can be.

A therapist can help us sort out relationships and our expectations.
There are lots of compassionate people here that can make the load lighter by sharing and caring.
Many people find compassionate, caring people here at PC. Some people find the forums give them the compassion and empathy they seek.
