Good afternoon everyone,am a young lady of 27 year

Good afternoon everyone,am a young lady of 27 years,I dated this guy 6years ago,we parted for a while when my dad had stroke before we could come back together he got an admission to further his schooling abroad,two years ago he came back to Nigeria and invited me to come over which I went and met his parents after a long time,few days back he left Nigeria after then we started talking and checking on each other at that time I had nothing serious (relationship) so he finished his program last year and came back last year October due to I was busy at school I could not go so I went in November,after my exams in December I went to see him again and this time we had sex, I never border talking pills because I had hormones issues which am still treating and going for treatment because have been told I might not conceive but have been treating it medically,so last week I feel weak and tired as if I want to fall ill so I went to the lab to do a malaria test I was now advise to go for a pregnancy test which I did and it came out positive,immediately I snap the result and send to him,the first question he will ask was if I never took pills,I just told him I did that may be the pills did not work,so he said he understand,after then he refused to pick my calls or even respond to my message he will just read my messages on WhatsApp and ignore ,I would have gone to his family house but they have traveled and I believe he must have left the house because of the situation at hand.pls advise me on what to do.thanks
