Summarize this article in one sentence.
Part of being a good boyfriend is staying loyal and committed to your relationship with your girlfriend. Avoid flirting with other girls or blowing off your girlfriend to be with friends. Show her you are committed by spending quality time with her and paying attention to her when you are out socially or with a group. Part of being committed to your girlfriend is also trusting her and not being too protective or overbearing. Try not to control her life or her decisions. Instead of policing her actions or trying to control her, support and trust her. Deepen your relationship by pursuing activities or interests that you have in common. Focus on things that you both share and enjoy. For example, if you both enjoy travelling, plan a trip together overseas. If you both like to watch movies at home, designate one night movie night and watch all of your favorite flicks together. If you and your girlfriend share a home, make sure you pull your weight. Split the household chores with her, such as taking out the garbage or cleaning the kitchen. Try to keep your contributions to maintaining your home equal and fair. If you both have issues around household responsibilities, make sure you talk about it honestly and openly. Work through the issues together and find a compromise where you both are happy. Keep your relationship spontaneous and exciting by planning surprise dates or leaving special gifts for her to find. Let your girlfriend know you appreciate her by surprising her on occasion.  You may surprise her with something simple, like a bouquet of flowers or a small gift. Or you may surprise her by taking her out for dinner or to do an activity that you know she would enjoy. Be open to your girlfriend surprising you with special dates or gifts, as well! Pay attention when she is generous and giving to you, so you can also feel appreciated and loved. Always thank her.
Stay committed to her. Find things you have in common and explore them together. Share household responsibilities if you live together. Surprise her with special dates or gifts.
