My ex did me wrong in alot of ways its almost a year later his stuff is in my house should i break it up?

ok I'm not an angel and won't act like im the total victim here ...we both weren't compatible with eachother..more so my break up with him derived from my aggrevation of him being married (he is an immigrant) to his kids mother...he received his green card in 2007 at the time he lived with me so I gave it over a year so the marriage would look convincing instead of him divorcing right away a year goes by he doesn't file..i kick him out the house but despite that we were still together and he filed in november of 2008..i saw all the legal work for myself..by july 2009 i questioned him about the process of the divorce and mind u i try not to ever bug him about it because i know the process is long..he would act very nonchalant like he didn't care about the process of the divorce it lead to a argument and we mutally stop talking..he text me a mth later saying how i should be with him, he cancelled the divorce after i broke up with him to retain his citizenship quicker..in the mix of that he met a columbian chick 3 weeks after we broke up, he was bold enough to tell me how he talked to her cause she had a nice body..even invited her to bbqs bringing her around friends i never met in the 3yrs i was with him! and how she spend the night being she live in jersey and he lives in the bronx but how she slept with his kids on the air bead..long story short i came into contact with her..both of them denied being together with eachother saying they had no chemistry and how she didn't like black men, she only babysitted his kids...well i cut off ties with both of them by December..but by January my ex and I would talk on the phone from time to time, me being dumb and hopeful i thought we would be 2gether, but our last convo he talked in a tone like he didnt want to hear from me like I was a piece of garbage despite we haven't had no disputes since last year..just wednesday though i finally paid attention to her myspace page profile pick that has been up for the longest..the skank that she is have a picture posted of herself in lace panties and topless covering her bust with her forearms i finally paid attention to the background and it was indeed my exes house..why a woman would lie for a man she is ing idk, i would never lie for a man i suppose to be exclusive with in the back of my head i would think he would want to bed both of us..it took all i can not to call him or her to not flip out..i been trying to keep very busy and with all the lies and betrayl..mind u he flirted with females behind my back online ready to meet them soon as we had a disaggreement when we were still together and we did have physical altercations I won't make myself look foolish and call him when he doesn't want to be bothered its like he hates me like im yesterdays trash and my self esteem is to the floor im so hurt..im looking at his reading gles should i just break them? throw away his work uniforms and cds? he doesn't call me...
