1. Heart shaped jewelry

Yes, this gift can be romantic and very pretty, but it can only be worn at certain occasions. As opposed to a nice necklace ( or earring set) with a general elegant design and a pretty stone. It all depends on if it's tacky or not.

2. Messages or phone calls at 3:00 am

I don't care how much you need to tell her you love her, it can wait until morning. Leave her a sweet good night text and then wait to leave her a sweet good morning text until morning is actually here.

3. Kissing her in the middle of a sentence to make her shut up when she's upset about something.

That's not sweet, it's a power play. You're telling her in that moment that you don't care about what she has to say. Wait until she's finished and then you can comfort/kiss her.

4. Solving her problems for her.

Following up the previous one, she doesn't need you to solve everything for her. She needs some form of comfort to help calm her after the initial shock of the event and then she will be ready to solve it on her own. She will ask if she needs you to help.

5. Picking her up.

Know your own body strength and limits. Some guys can do it and others can't. She won't love you less just because you can't scoop her up into your arms. You can sweep her off her feet in other ways.

6. Showing up at her house unannounced.

Please just don't. Unless you are long enough into the relationship that you have both established this to be okay (in some cases people give each other the spare house key), just don't do it. She might be in her pajamas or hanging out with another friend and it would be rude of you to intrude on her privacy like that.

7. Standing way too close.

Guys, if she's currently willing to hold hands with you and kiss you, then by all means, cuddle up next to her on a couch or something. But if she tells you she needs space, RESPECT THAT. You might think it's cute to hover, but it isn't!

8. Flowers after a first date.

Yes, it's cute, but it's kind of forward. What if she isn't ready? What if she isn't yet sure if the date went that well? Maybe wait until the third or fourth date.

9. Refusing to let her pay if she wants to go dutch on a date.

An oldie but a goodie. Guys, it's not a spite to your manliness if she wants to help. She just wants to help! It doesn't make you any less chivalrous if you don't pay the whole thing.

10. Public proposals.

We've all seen the videos on youtube or facebook where the guy stages this huge thing, either in the middle of a mall or at a sports game and gets rejected in front of everyone. Don't be that guy. Save yourself the embarrassment and plan a lovely dinner or fill a room with candles or something.
