Ah, the mysteries of love.
Or... they would be mysteries if there wasn't a ton of research on why people tend to be more attracted to each other, the different types of love, and reasons for conflict and unhappy relationships.

Think of propinquity as proximity's close cousin.
Proximity is purely about the distance, while propinquity is about frequency of seeing and interacting with someone.
Just as we are more likely to get into a relationship with a close proximity, the propinquity effect says we are more likely to get into a relationship with someone we see and interact with often.
The mere exposure effect is similar to this. Basically, the more you see something the more likely you are to like it (as long as it didn't cause a strong negative reaction the first time you saw it.)
This theory states that there are 3 things that effect a relationship:
Depending on the level of each the type of relationship you're in will change.
High passion, high intimacy, and low commitment will lead to a romantic relationship (typical college relationship), while low passion, high intimacy, and high commitment will lead to a companionate love (think a happy, old couple).
This theory says that during your infancy you developed behaviors that affects your relationships throughout your entire life. You created a "model" of a good relationship and followed that model.
There are 3 types of attachments:
However, with work these can be changed. Just because you're not "secure" doesn't mean you can't change your behaviors and eventually change.
