I'm becoming depressed

So I met this guy in 2013 after my high school,we became friends but he had an interest in me we became friends and later started flirting,I had feelings for him and I bet he had feelings for me too.
so I dropped my boyfriend at that time and went to him.previously while we were still flirting I became pregnant with my boyfriend and I aborted because I wanted to be with him and other reasons.so he found out I had been pregnant before and as soon as we had started our thing he dumped me.i cried for days tried to get back with him but in vain..time passed by like 7 months and again he came back to me.in those 7 months I had dated another guy he was like a rebound found out I never loved him then dropped him and I got back to this guy let's call him Ethen.
so at first things between me and Ethen were great and it was long distance because we both study in different universities and it's only short distance when we home for holidays
2014 around July is when we begun our relationship while we were home for holidays after which we both went to school.After like three weeks he posted a picture of him and two ladies pecking him on the cheeks,I got so mad about it when I asked him he got all furious I must admit that on that day my rebound ex came to me and I felt safe so I slept with him..days later I felt guilty and went to my ethens place I wanted to tell him what I had done but something held me back
immediately he saw me we kissed and had sex we never talked about what had happened
that's when I started having trust issues,come Dec 2014 he was cold to me I realized he had been flirting with some girl ivy the went too far that in 2015 January and February Ethen was cold to me and he treated badly that's when I had my first suicidal attempt after failing to die I went to ethens place yet again he had sex with me and I thought we were fine..weeks later after I got back to school he updated a status on whatsapp on how he loved ivy I didn't ask anything so when we were home for holidays in June we broke up because he was flirting with an ex.then a month later we got back together because I was pregnant with his child which we both agreed to abort.
things were all fine until November when I told him I had slept with another guy in 2014..he got mad at me for the entire year until 2016 when I developed cervical cancer..so we've been together for long and then he was ready to start a family with me..we because so close that the relationship was smooth..we loved each other.i became pregnant and unfortunately this time I miscarried for the whole year we are just fine
then come 2017 he wakes up one morning tells me am a cheat and I have several fuckboys he dumps me he hasn't spoken to me in days..I've been desperately calling him and texting him.so yest was my birthday and I got a text from him wishing me a happy one but he blocked me later on
this guy and I have been through alot..we've been broke where we even slept on the floor with him and we've sometimes stayed hungry because we spent al the money on transport charges
I love him so much I haven't seen him in a month and it's driving me crazy
i cry every day please help me
