You shouldn't have to prove you were just saying "love you" to your mom unless he had already given her a reason not to trust him before. Regardless a guy would have to be pretty stupid to even say anything to another girl he was seeing while knowingly on the phone with his woman. seriously sometimes women are too paranoid.

If your significant other is on the phone saying 'I love you' and you have no context it's understandable to be worried. Granted not so much as to dump someone. Also previous fmls have shown that people can be truly stupid about cheating.

I don't think if I heard my guy saying "I love you" to someone on the phone I'd assume he was saying it to another girl. After all he has a family. If you feel that insecure with someone they probably aren't the one for you

I'd be freaked out if I heard my boyfriend saying that simply because I know he doesn't say it to anyone besides me, including family, so unless the OP is like that which he clearly isn't, then she might've been looking for some excuse to leave

If you can't give him a little trust until he proves otherwise you shouldn't be with him. You can ask, he will tell you. He shouldn't have to go through hoops to prove anything. It seems like people assume the worse. You have to have trust when you date.

That's not the definition of insecurity.

I don't see why you're getting thumbs down. It really isn't the definition of insecurity.

28 - Not necessarily. "Insecurity; Noun, plural in·se·cu·ri·ties. 1. The lack of confidence in oneself; self-doubt: He is plagued by his growing insecurity. 2. The quality or state of being insecure; instability: The insecurity of her financial position. 3. Insecurity brought on by another person; the lack of trust in someone other than oneself: The many insecurities of life."

OP may not be a "grown up." which would actually explain his bat-shit crazy GF.
