Cheater: Tips how to tell you Boy/girlfriend is cheating on you

You have to be careful with this. Sometimes you can't tell. If you really can't trust them then you should rethink the relationship.

Honestly that can get complicated. There are a ton of ways to read dishonesty but remember this. Mistrust breeds mistrust. Make sure you can trust the person. There are people who are so good at cheating that the best tips won't help you.

I just need signs or clues because of her I haven't girlfriend for two years when she broke she try get the boy who she use to cheat on me to beat me up(but she didn't know my friends was near by). I don't something like that to happen again to me

Well you shouldn't live in fear. As Lagannfan said mistrust breeds mistrust. All you can do is when you are ready and find someone that you love and that you are willing to put your heart on the line with do so. And let them show you that they love you. A good partner will understand and show their love and prove you can trust them with their actions. Just make sure you are ready to love the person back and let go if they show you they don't love you.

I notice the little things. I.e. they start to hide their phones when you are around. Also they go through your things and claim you are up to something. They become a lot more jumpy too, and upset when you ask about or even speak the word "cheat"

Yea ya cannot go into a new relationship watching your new G/F looking for her to cheat cause a new relationship is hard enough to nurture without looking for phantoms and ghost of the past to come back. I know it sucks but best thing to do is just be yourself and listen to her. If it is meant to be should be smooth if not try to end on good terms is best I can offer.

Making excuses to and wanting to spend less time with you, being less touchy/feely than before, being more secretive and getting more defensive if you ask any sort of probing questions. Not that those signs always mean cheating, but it's just from personal experience and what I've seen others do when they have been unfaithful.

If they dont talk too u as much? XP if they avoid u or if they r real protective of u touching their phones and computers
