Pls everyone should advice me on time

Good afternoon sir, please keep me Anonymous, I am very sad because I have been dating this guy  for over five years now and the fifth year I asked him when he is ready to take the relationship to the next level and he will say nothing, after some months I asked him the same question again and he said I should inform my parents that his coming for introduction and I was happy so I quickly inform my mum because am the only child of my mum and I lost my dad when I was still little so after my school last year my mum has not let me eat in peace asking me when to bring a man home so when he said I should inform my family I was happy, the truth is I  love this guy so much and he love me too his family accepted me the very day I stepped my foot in their house, sometimes his mum will tell me to not worry about my resumption tat she will take care of it back then when I was still schooling, the family really loves me, so in August last year we did   our any engagement been  done I was little worried that he did not ask me to marry him properly but he said what matters is that he choose me so we discussed our marriage plans and he said we will get married December same year but it didn't work because of finance so I asked him when it will be possible again he said  march and now we are in January so I told that we should start preparing now and also in inform  our families so they can also be preparing but he boldly told me to stop disturbing him ever since then he stop calling me ,no text,he doesn't check on me  again so I was

Worried and decided to cheek on him and I checked his phone that night and I discovered that he was cheating on me with a lady so I chatted the lady using his phone and also called her to confirmed and when he came in he wasn't apologetic at all so I told him to tell me way forward with the wedding plans before the end of January but nothing, no call or anything,I have been praying and fasting but gotten nothing, please how can I handle this situation sir.

I’ll be in the comment section.
