Do not open old wounds. If she has shared something intimate with you, you will damage your relationship by using it against her.
Some people are more sensitive than others so be aware of what triggers will push her too far. For example, some girls may find playful flirting with strangers amusing while others may find it very disrespectful and will end a relationship over it. Tread lightly.
If she says that she does not want you to interact with someone, do not use this against her. Her paranoia is already at high alert so breaking your promise will do irreversible damage. Avoid using an ex to make her jealous. Knowing that you already have had a romantic relationship makes it easy to believe you can rekindle it at any moment. Do not mention high profile friends. Whether you have mutual friends that are on tv, play professional sports, or have high paying jobs, their social status makes them an alluring romantic pursuit. Your girlfriend may easily become jealous if you show too much favor to a high profile friend.
Don’t make her feel like a burden or that she isn’t fun to be around. This is just meant to show her that you are fun to be around.
Be careful if you get too close to her best friend as it may cause deep emotional damage. Learn the dynamics she has with her friends so as not to open up deeper issues. One of her friends may have a history of stealing men.
