1.他比平时明显地更加关心和关注你，尤其是那些他以前没有投入过任何注意力的方面。其实这是他内疚的表现，因为在发生“变心”的最早阶段，其实是一种潜意识的补偿心理，这样主要是让他自己觉得好受点儿。
2.莫名其妙地开始给你买礼物，可他本身并不是一个浪漫或者爱这样讨好**人。
3.他突然变得喜怒无常，经常没事找事，无论你做什么他总是能挑出毛病。这是人在心虚状态下的反应，他潜意识里觉得自己“错”了，所以想证明你也“错”了，这样在心理上他就会产生一种“扯平了”的感觉。
4.他的行为会让你心生疑虑，可能你也说不清到底是哪里有点不对劲，但就是觉得“怪怪的”，这个时候，不妨相信女人的直觉吧！一般都非常准~
5只要你一“反击”有时候甚至只是撒娇装装样子，他就马上提分手，根本没有心思和你沟通，也不会提出任何解决问题的方法。
6只要你要离开他一段时间，比如出差、旅游之类的，他就会显得莫名兴奋，当然不是那种“欢送”般的感觉，而是变得比较情绪化，比如不停地帮你准备行李，对旅程过分关心，或者表现出夸张的沮丧。
7.变得冷冷漠。变得不爱说话，也不爱交流。但是在此期间并没有发生不愉快的事情。
8.品位突然发生变化。例如开始听和以前不同的音乐，看不同的电影或是书籍，甚至会关心以前全然不想理会的东西，比如娱乐明星或是猫猫狗狗之类的。
9.突然开始自信。如果您并没有发现有其他事情激发了他的自信心，那么从某种程度上讲这很可能与从另一处获得的心理满足有关。他似乎从另一个地方获得了一份新的认可感，从而提高了自己的自我价值感？
10.starts to criticize you directly and say "I hate such things." This is a clear indication that he is trying to shift the focus away from his own infidelity and onto your supposed shortcomings.
11.The frequency of his visits or calls suddenly increases, but there's an undercurrent of guilt in these actions.
12.He starts to show more affection towards you, especially in public, as if he wants others to see how much he cares about you.
13.You notice changes in his behavior around certain times or places that seem unrelated to anything specific happening between the two of you.
14.The way he interacts with other women changes; for example, they might be overly friendly or flirty around him when previously they were just acquaintances.
15.Your partner seems particularly interested in your social media activities, constantly checking up on what you're posting or who's commenting on your posts.
16.Suddenly becomes very protective over your relationship status on social media platforms like Facebook and Instagram by frequently changing it back after someone else has commented something negative about it (this could be another sign of insecurity).
17.Starts talking about divorce lawyers out-of-the-blue without any apparent reason for doing so (a possible attempt at making himself feel better).
18.His language becomes more aggressive during arguments with little provocation from yourself; this may indicate that they are trying not only control conversations but also push boundaries further than usual due primarily because their mind has been preoccupied elsewhere since becoming involved with someone new outside marriage vows?
19.Your partner starts acting possessive towards other people - whether friends or family members - even though there hasn't been any known issue within the relationship itself before this point either!
20.Becomes extremely defensive whenever confronted about strange behaviors mentioned above while denying all allegations entirely which shows distrustful nature as well., There was no evidence suggesting betrayal existed until recently? So why do I need my trust shattered now?
These 20 signs are some common indicators that can reveal if a man is cheating on his partner - regardless of whether it happens right here at home base camp called “marriage". Keep vigilant always remember those subtle clues might come across quite innocent initially yet add up later down road leading deeper into trouble waters ahead...
