1.You Face Constant False Accusations
If you are consistently facing 21 questions every time you hang out with your girlfriend, there is something wrong. You should not have to answer a bunch of questions regarding where you were and what you were eating for dinner. These questions may seem harmless but they will manifest into accusations very quickly. If you can’t pick up your phone without being accused of cheating, it’s time for you to get out. If you catch her going through your phone/email/Facebook it’s also time to leave her. There is evidently no trust in the relationship and it is bound to fail.
2.She Has an Established a Set of Rules For You
If you’re not allowed to go to the bar without your girlfriend, or for a drink after work with co-workers, it may be time to look inward. Relationships are about two people’s lives intersecting, not one person strictly controlling the others. If you are a laid back guy and your girlfriend is constantly setting up all these unrealistic boundaries, it’s time to leave her.
3. She Gets Destructive
Every relationship is going to have its rocky moments. Fighting can often result in a strengthening of the relationship. Though if your girlfriend gets destructive when you guys have a disagreement, this is unhealthy. She may get physical with you (slapping and shoving) or with things in the house (breaking photos/furniture). If she is hulking out all around your apartment, she is probably in need of some anger management treatment. Do not suggest this to her while she is in the midst of destroying the kitchen.
4. She Refuses to Be Alone
You should be part of your girlfriends life, not her entire life. If she demands your constant attention, this is not only a stress on you. It is also a surefire sign that is she is crazy. If she blows up your phone with 20 straight missed calls or shows up randomly when you are hanging out with your friends, alarm bells should be going off inside your head. I would recommend not only getting out of the relationship, but getting a restraining order may be a good idea as well.
5. If She Pollutes Facebook with Her Emotional Life Story
If employers scope out Facebook profiles before hiring people, why shouldn’t you do the same with regards to dating. If you go on your girlfriends Facebook and she has twenty statuses in a row complaining about her family, friends or you, there is a problem. If your girl has a issue, she should tell you or her friends, not post it on her Facebook wall. Also, if she is posting subliminal statuses/tweets saying things like, “Sometimes I wish you would just be different.” You should be thinking about different exit strategies.
