It doesn't matter who does it, or the reason that leads to it―cheating is something that cannot and should not be tolerated. It destroys the very foundation that a relationship is based on, leaving irreparable cracks.
It is usually right to trust your instincts when you notice that something is amiss in your relationship. Your otherwise-loving girlfriend seems to keep a distance from you, or you just begin to notice certain subtle oddities in her behavior. If these things seem to ring a bell, here are a few other things to more or less confirm your worst suspicion.
She rarely responds to your phone calls
Even though you've tried calling her many times, she is repeatedly not answering your calls. What's worse? She doesn't even return them. And when you ask her about it, she will always have a work-related story ready. Guys, this is the age of instant communication. If she really wanted to call, she would have called.
Lying about her whereabouts
People who are cheating have this obvious need to create alibis, in case they are confronted. Therefore, when your girl regularly seems cagey when asked about her whereabouts, she is probably meeting someone behind your back.
The fights increase
All of a sudden, everything and anything you so seems to annoy her. She picks up fights like she never used to, and what's more, she is not interested in making up as well.
It's a red flag when couples stop talking to each other. It's one thing being comfortable with the silences, but a complete lack of communication indicates that she may have found a new confidante to share her thoughts with.
Being overly cozy with you
When your girlfriend suddenly changes her behavior and begins to shower you with extra love and attention for no apparent reason, it may suggest that her guilty-as-hell subconscious is trying to make it up to you. It's actually strange, and can't be seen as an actual sign of cheating, but when observed in conjunction with the other signs, it does hold true.
She is not even interested in cuddling
Physical intimacy takes an obvious beating when a partner is being unfaithful. It can also be an indication that she's no longer physically attracted to you.
The above signs will help you find out if she is cheating. However, if you are still not sure whether she is cheating on you, Here's what you do:-
Assess whether she is still in love with you
Try to answer this simple question. Is she still in love with you? Apply some logic. If the answer is yes, then there's some point to the relationship. If the answer is no, then what is the point in you taking it forward?
Assess whether you are in love with her
Think of the reason why you loved her. Think of the things because of which you fell in love with her. To quote a cliche "love is all you need for a relationship".
