Oh to be young, and to feel love's keen sting. Most likely, the vast majority of people reading this will have experienced heartbreak at some point in their lives. Heartbreak is a natural part of life, and, though it is hard to deal with - particularly when we are young - it is possible to come out of the other side a stronger and more independent person. Unfortunately, some break ups are messier than others, and as such can leave scars on us that last a long time, if they are not acknowledged and tended to. When we think of messy break ups, most of us probably think of one partner cheating on another (though this is by no means the only way that a previously loving union can turn sour). It is important to note that, Tom Martin, the private eye in question, states that one or two signs in isolation are not usually a problem; but, "“If you have three or four, you have a problem”. Here, then, are his tell-tale signs that you should be watching out for. 1. Changing habits 2. "I'm going on a business trip", repeatedly  3. Absences from key family events or holidays  4. Coming home later than usual  5. Out of character over-spending 6. A change in appearance  7. Missed calls from unknown numbers  8. Coded text messages 9. A lessened desire for sex 10. Clear lies  11. Becoming overly defensive [[instagramwidget||https://www.instagram.com/p/Bl31wzgnLAo/?hl=en&taken-by=couplegoals]] 12. A short temper  [[instagramwidget||https://www.instagram.com/p/BmBWmjInCDH/?hl=en&tagged=couples]] These are some signs to look out for, but remember: communication is key to success in any relationship, and if your partner has been acting a little distant lately, it's probably best to talk to them about it first before jumping to conclusions.

These are the 12 signs your partner is cheating on you, according to a private eye
