Why do some girls start acting crazy once they fall in love?

[Answered on Quora.com by Ella González]

It's insecurity, and it's something to get past if you want to have sucessful relationships. It's not easy, and guys do it, too, just in a different way. Consciously or subconsciously you're taking every last sentence and action and deciding if this means he's losing interest in you. This can quickly become a vicious cycle that ends with him actually losing interest in you, so do be careful.

To change it, stop and think why you're angry, then decide if getting angry at him for his actions is actually solving anything. If him not saying 'goodnight' really is a sign that he's losing interest, what do you gain by getting angry at him? You might fix a symptom, and that's it.

Next, get in the habit of actually just talking about things. Realize that chances are, everything is fine, and if it's not, a fight won't solve anything. If he is feeling like there are problems in the relationship, he's more likely to tell you if you bring it up in non-confrontational way. It's hard enough talking about this stuff, believe me. It's even harder when you're worried about getting your head bitten off.

Finally, listen. You don't have to immediately respond to things. If he's constantly saying you are misunderstanding what he says, then reformulate what he says and repeat it back to see if you are correct. And when fights happen (and they will), don't fight dirty (don't throw insults, say hurtful things, etc).

Honestly, a good start would be to just get out in the open how you feel. Tell him you recognize you're being crazy, that you don't like it, and you want to change. You're not telling him anything he doesn't already know, and he's going to feel a lot better if he can actually talk to you about it. And give him a chance to talk, listen and don't get defensive. Save the explanations and interjections until the end. Acknowledge what you think is reasonable, explain (but don't over explain) what you don't think is reasonable.

Communication is better than no communication all the time. At best you solve problems before they become huge. At a minimum, you aren't blindsided by huge problems that aren't fixable. It will reduce your insecurity, too.
