Search Results: prove to my boyfriend that i love him

So my boyfriend disappeared last year for about 3 months when he back he told me the reason is he was in prison. I forgive him but he wants back with me. So in the end of January I back with him cause he kept showing that he love me. in March we fought cause he lied to me. So I blocked him , but he reached me on my email, Instagram, etc. So my heart melted. I forgive him again. In may we back again together. Short of story , I still feel afraid if he disappears again. Cause in June he disappeared for 5 days and the reason is he left his phone in train. But the security found is and kept the phone. I was asking why you didn't try to contact me? Ex he can texted me from his roommate just to tell me that his phone lost. And he said his roommate was in other country. And last week he disappeared again for 8 days. he texted me last night "sorry my phone screes was broken , I think I have many bad lucks. How is everything?" I just read the text. I dont know what should I do.
Should I trust him again? Should I ask him to give me the prove? If you think I should leave him tell me how?

I have a four months foreign boyfriend I have been hiding because of his international criminal records. He theft million dollars 5 years ago from an international bank in Japan.
Now he is living in Malaysia for already five years and we happen to meet each and fell in love. We do really love each other.

Until such time my family caught me I have a boyfriend. At first, they like him because he seems to be serious to me but later when my family find out he is a wanted international criminal, my family changed and hated him.
My family wants me to go away from this man or else they will make case for him. And so I did.

Now my boyfriend don't want this to happen. He wants to marry me to prove that he loves me. What shall I do. Should I marry someone a criminal? Doesn't it matter because we both love each other?
