1. Altered Schedule
The first sign is the altered schedule. Suppose that your partner has never worked late. However, recently, she always says that she needs to work overtime to finish her overloaded work. Or, your girlfriend used to have no habit of doing sports. Now she goes to the gym with increased frequency. These are both signs that you should keep an eye on. Although an altered schedule does not necessarily mean your girlfriend is cheating, you should be aware that these behaviors are unusual, especially when no good explanations are given.
2. Faded Emotional Intimacy
The second sign is faded emotional intimacy. Emotional intimacy plays an important role in fostering security and mutual trust. A strong level of emotional intimacy indicates that the couple is mutually in need of each other, and there is a deep bond between them. A couple lacking emotional intimacy may have a struggling relationship. If your girlfriend stops expressing her thoughts or to you, that's a strong indication that her attention has shifted from you to a third party.
3. Being Secretive with Her Phone
If your girlfriend is cheating on you, she will check her phone at any time, and prevent you from seeing the messages in social network apps like WhatsApp. If your girlfriend holds her phone everywhere she goes, even including the bathroom, it is a sign that she is holding back from you. If she changes a new password for her phone, you should also stay alert.
These three signs are what you should watch out for in a relationship. When spotting these signs, you should be conscious that it is possible that your girlfriend is cheating on you.
