I dont get it

I dont et why ppl would like to screw up someone who cares about them life , revenge looks like the main reason . each time when I think that I sorted thing out , I found out something I have never expected it coming . how can someone act so cool with u & in the same moment do the opposite , the ability of how ppl can lie & cheat I didn't relies it untill today . it's like '3r8t in a very deep see & I couldn't watch or see or understand any thing  . I just got why I had all these nightmares about him , cuz what I knew wasnt the truth , part of it was made up just to make me miserable & when she knew I'm over it she pushed my memories with him
I think no night mares in my sleeping today , cuz the truth appeared , but still I can believe how someone can be two faces this much I plan this good for ruining someone life .
I guess now that what was all about yesterday & that why today I got this nervous & replayed the msgs , that way I tolled him go to hell & so on although I dont usually do it unless I'm so angry , just to know the truth somehow , looks like in the end allah ma yr'6a 3la 3bdah y3esh mhmom or 7d ya5thah b'6lm , I felt so bad when I know someone tolled him so cuz I didnt speak about him , I used to tell bushra take a gd care of him & god knows what did she told him !! glad that every thing is clear , sad that I do trust ppl who dont deserve my trust , I lose others who I let them down sometimes , I take it easy on my heart , but my 7rara goes up & I feel the sickness in my heart spread to the rest of my body . I dont really know what to do any more , but I do know that I'm keeping my self away than ppl cuz I just cant take it any more , gd night
