During the "infatuation phase" of most relationships I believe most people just "roll with" whatever ever unfolds.
If they are super attracted to a (new person) they will say "YES" to just about anything in order to not "jeopardize" their "opportunity" to get to know them better.
You'll see women attending sporting events they have no interest in and guys attending musicals or going shopping just to get closer to the new person. The "infatuation phase" generally lasts up to 6 months if a couple consistantly sees one another. It can last longer in a long distant relationship. It's during this phase where more often than not the first "I love you" is expressed by one or both parties. Naturally it's during this phase when both people are bending over backwards to "impress" each other that we start to believe we have found our "soulmate". We really believe we have found someone who enjoys doing "all the same things we do". Everyone "agrees" in the beginning of a relationship or else a relationship would never come about.
The next phase which I will call the "attachment phase" begins once we know our mate is "emotionally invested" in the relationship. We express our "authentic self" confident in the knowledge that we won't lose our mate by saying "No" to a variety of things because they would be hurt by the breakup as much as or more than you.
Love is not "blind" we just tend to put up with more crap from the people we love. We justify it by saying no one gets to "have their cake and eat it too". Unfortunately many of us have learned to accept crumbs. It takes more courage to walk away from an unhealthy relationship than a lot of people have. Quite often it's NOT the person who is mistreated that ends the relationship but it's the one who is doing the mistreating. When someone believes she/he loves their mate "too much"...etc What they are really saying is "I Don't Love Myself Enough" to walk away.
