I think there are only two different views that may result to a couple who both gamble. One is that they will have strong bond that may result to stronger relationship. Their hobby, which is gambling may be a good experience that they may enjoy and share together. On the other hand, this may also be the cause of their misunderstanding that may affect their relationship
I have a little bit different opinion in this regard. Even if the couple has a strong relationship between them but when one will lose money or something else to beloved one, there will be a feeling of distrusting coming from inner side which will be saying to him that hes not your faithful friend. I think that feeling will make their bond weaker than it was before gambling. I am saying this because I have experienced this thing many times in my life.
I don't really like this idea of having a partner with same disease as me.
That sounds like a great thought. Having your partner into a profitable business must be a good idea but not into same frustrating area where you may catch your life time failures too.
