I met this guy in the mall. I had been having alot of problems with my ex and needed a distraction?

So we ended up spending time together and eventually became a couple . Everything was wonderful. We were falling in love. He met my parents and his family loved me. I noticed the followin month my period was late so I told him. I had nvr had this problem before but, he insured me not to worry and that the next time he saw me he would buy me a pregnancy test. I felt relieved. he told me "whatever you choose to do I will support you 100 percent.'' that was on a monday. On that friday i became very ill and i txt him telling him i was too sick to go to skool and that he needed to buy a pregnancy test asap! He txt me "dmn". And i haven't heard from him since! No phone call no text message nothing. Why? After we told each other we loved each other and spending all that time toqether why would he just up and leave like that? He told me to love him and be there for him but he wasn't even there for me when i needed him the most. Why did he do that to me?& in the end my ex who ihad left for this guy is bein here 4 me
