Rehab is a time in which you are learning to cope with the ups and downs of life without turning to substances.
These emotions can distract you from the work of changing your behaviors and your coping mechanisms and can put you at risk of relapse if you experience rejection or abandonment.
Another thing to keep in mind is if a new partner picks up a drink or a drug, it will be much harder for you to resist.
If you are compelled to form romantic relationships and find it very uncomfortable to not have a partner, you may need to consider that you could have a problem with love addiction.
The time you spend in rehab is an important time in your life.
Turning to love or sex to avoid dealing with pain and problems is just another form of addiction.
