My boyfriend sent me a short message with a strange number, saying that he wanted me to be his girlfriend …

I want to say three things. First, your boyfriend cares about you, so you should cherish it. Second, you must let him know that you are unhappy, untrustworthy and hurt when he does this. Seriously, or there will be a next time. Third, in a long-distance relationship, trust is very important. Without trust, there is nothing, but you should also remember that it is difficult to learn to keep a love, but it is worthwhile for a boyfriend who cares about you so much.
