Are your sick and tired of your spouse, boy/girlfriend, partner, significant other? Do they drink/drug to excess and repeatedly promise to make changes in their usage of substances?
Why has it taken so long for you to admit this to yourself? Why is it so difficult to either verbalize your true feelings to this person or to make a change by leaving the relationship?
It is never ALL bad. Every relationship has some healthy, good components within it, yet sometimes there comes a time when the bad outweighs the good.
Do you feel stuck in your marriage or relationship? Do you wonder about possible options or alternatives? Do you fear being alone? Do you hope for change year after year? Are you willing to settle for the status quo?
These are good questions to discuss with a therapist who might be able to give reflective feedback on the truth of what you the client might share.
It takes courage to seek help. I encourage you to call a counselor, it is a positive process which may lead you to more healthy relationship decisions.
