Relationships are about confidence and communication, but over period that can erode away. You may start out loving one another but those emotions can fade over time. You get bored with each other and want to experience new things. For this reason most affairs occur.
There are ways you can find out if you have a Cheating boyfriend. They are not exact or set in stone, but they can be fairly decent guidelines to help you determine whether or not your man will someone else for his needs.
If he comes home late this could be a sign he is cheating. Now clearly it is not if he comes home late once in a while. There are a lot of reasons he may be late, from working late to having to cope with traffic. This only becomes an issue if he does it consistently.
Another thing you can look for is definitely what he does when he gets home. If he goes straight to the shower, this can be a tell tale sign he is having an affair. If he is cheating on you he will want to hide the evidence, which is why he goes straight to the shower. He will probably avoid you at all costs as he heads for the shower.
If your romantic life provides dwindled out, this is often another sign. It is not concrete evidence that he will be cheating, as there can be other reasons why your love lifestyle is enduring. If this is the only indication you recognise you might want to simply talk with him about it as there is probably another reason why this is happening.
If he causes excuses for not spending time with you or generally just avoids you. If he is having an affair he will want to spend time with that person over you. So if he constantly comes up with an excuse when you try to do something with him, this can be a pretty big reddish flag.
Something you should keep in mind if you suspect you have a Cheating boyfriend is to play dumb. You can not demonstrate anything if he is trying to hide it, so to capture him you have to be smarter then he is. If you pretend to end up being clueless and not suspicious at all, he will lower his guard.
You can lull him into a false sense of safety by doing this, he will think he is some sly devil who is getting off scott free but in reality he is falling right into your trap. Eventually he will make a mistake, leaving a specific text message on his telephone or enabling you to answer a contact from his mistress.
Once you get the evidence you need you can confront him on it and get the course of action you deem appropriate. Whether you dump him or offer him another possibility is up to you. Just remember that not all men cheat, and you would not want to wrongly accuse your boyfriend of being a cheater. So ensure you get reliable evidence before making a move, normally it might be you who ruins your connection.
