Don't over give save the gifts for anniversaries, birthdays, and Christmas. When your just starting out you can have a one month gift then a three month gift. Make it thoughtful.
Be yourself
Don't fall into reputation. Example always going to the same restaurant because you both love it there. It is ok if you get a bad experience here and there. If she is talking negatively about the restaurant don't take it personally. Same goes towards a movie etc. She is just sharing her feelings to you it is a good thing.
Don't always be a problem solver to her problems. Especially when she is having a bad day etc. This is the time to listen to be there for her. Give her a hug let her know you care about her.
When she doesn't feel attractive tell her she turns you on and give her a hug and a kiss.
Women tend to give a lot of themselves and unknowingly expect more in return. If she is feeling resentful let her know who ever she is complaing about how lucky they are to have her in there life. Let her talk and listen.
Her emotions and attraction for you grow as time goes on. Women are like ovens that get hotter over time.
Express your most positive self. Don't talk about yourself too much. Listen to her.
Questions tell you when it is your turn to talk. If you ask her a question make sure you let answer.
Unlock the car door for her. Make sure if some situation comes up that she feels protected by you. If you are going for a walk and there is a lot of busy traffic give her the other side etc.
You are going to be like an elastic band when it comes to being interested in her. Know that and understand it. It is important not to overly push the relationship forward too soon. Moderation is important. I know we love passionate moments but after you have had one don't try to keep outdoing it the next day.
Spend time with friends and family. Have her spend time with you and your friends or vice versa after you are comfortable with her.
Don't stop working on the relationship. That doesn't mean going out of your way to impress her. You have to be the person you are always going to be in the long run but pursue her.
In other words don't change keep pursuing her the same way you did one month into the relationship to your 90th year.
Become more serious after you know your levels of attraction with her and this takes time. Physical, emotional, mental, and spiritual. Try to work on the mental attraction more then the physical at the start. Then work on the emotional more.
Physical chemistry creates desire and arousal.
Emotional chemistry creats affection, caring, and trust.
Mental chemistry creats interest and receptivity.
Spirtual chemistry opens our hearts, creating love, appreciation, and respect.
Just be real!
Make sure you are in a give and take relationship over time. Don't be the only one working in the relationship.
If you did something wrong don't try to cover it up with a long conversation of why. Tell her you are sorry work on it.
Complement her on anything she invests a lot of time on.
Don't be needy
