How can a guy make a girl feel more secure?

The healthiest relationships are built on a strong foundation based on confidence in your significant other's loyalty. Without complete trust & respect in any bonding with another person whether romantic, friendship, etc. That "relationship" is plastic and basically never existed-its more for title, self entertainment, or other issues that people may have that's out there. It doesn't take much to make a girl feel secure. Texting "hi" would bring a smile to any girlfriends face. ,Its all about having common sense,too. Don't do anything that would genuinely hurt the person you care about which could forever change the way she looks into your eyes. Also, relationships shouldn't be stressful or "hard"-maybe you need to change your attitude towards building in the relationship. Giving personal undivided attention doesn't define you as weak, or a sucker. It actually shows being unselfish.

Simple, don't do anything that would make her not trust you. If you care for her, let her know. You don't have to tell her every second of every day, but make sure she knows it. I feel secure just knowing that my boyfriend loves me and knowing he has never done anything to break my trust. And for that reason, I am very secure in our relationship. All you can do is trust someone, and you can't be worried about what might have happened or could happen.

Girls are very intuitive. Mostly a girl feels insecure when their guy is not very into them. So, before you try to change who you act around your girl you might want to think about the possibility that your going out with the wrong types of girls who aren't making you feel interested, inspired, and infatuated.

Now if your just a stupid boy who has no idea what's going on because your in love and passionate and excited to see your girl every day then here is your advice.
Hugs- hugs are the greatest invention and giving a good solid hug to your girl is a great place to start. Pick her up and spin her around when you hug her or just simply don't let go for a really long time. Kissing- when your kissing make sure to do it with passion. Look at her after a few minutes and just LOOK at her, meet her eyes and stay there for a few moments. Call HER; make sure your calling her at least once a day and telling her how things are going. Send her a random txt message saying how you can't wait to see her. Most importantly. Make sure you tell her how you feel. TELL her how you think she is awesome and pick out an example of her awesomeness. TELL her how you can't wait to see her, how you respect her, how you are inspired because of her, how you need her hug when your day is shitty, how you thought about her because you saw something during your day that reminded you of her. Communication is key. You should also never stop trying to impress your girlfriend, take her on dates, have fun together.

Another tip is not to spend time with other girls who you might find attractive. You can have friends who are girls just make sure your girl and those girls get along and make sure you don't flirt when having fun with these girls.

Be nurturing and tolerant. If she has an insecurity about her body, compliment her on features you really like. If you think of her during the day, call or text her to tell her. If she worries about your girlfriends, put her mind at ease by taking her along for some outings.

Essentially, just do what you would like for someone to do for you in that situation. That is the nurturing part. The tolerant part is dealing with the stressful aspects which at times can occur and hopefully in due time she'll be more at ease. If not then those girls are quite possibly addicted to the drama.
