There is a difference between accepting and just “tolerating” your partner. Relationships are hard. You are each your own person, you have your own personalities, your own similarities and differences.
Love and Kindness
When you accept your partner you are wholeheartedly loving and receiving him/her. Acceptance comes from love and kindness. It comes from the heart. When you accept someone you have tolerance built-in. You are accepting your partner as they are and tolerating their imperfections because you love them and appreciate them. If you agreed 100 percent with everything your partner did it wouldn’t really be much of a relationship. No one is perfect. Everyone does things we don’t like/agree with but when you really love someone you learn how to tolerate those things. At least when they aren’t detrimental to the relationship as a whole.
On its own tolerance doesn’t come from love or kindness. It is not stopping the other person’s behavior. It comes from external motivation — whether it be to not get into trouble or receive judgment. Tolerating another person often has resentment. It does not come from the heart. It does not come from a genuine concern or care for the other person. It comes from personal fear or gain. If you just “tolerate” your partner or their behavior you don’t really care about the backbone of the relationship, which is acceptance.
In situations where I see a partner is just “tolerating” his/her partner’s actions, I encourage them to talk about it. To try to work towards acceptance. To minimize resentment, which can overtime build and ultimately destroy a relationship.
