I'm so sorry to hear about your difficult situation. My thoughts go out to you.

In terms of figuring out what your feelings are now, I'm wondering if you have you met Yousef, Hakim, and Hussein in person? Have they been able to travel to you, or have you been able to travel to them? In my experience, being in person with someone really helps clarify how you feel about them. Also, do you feel ready to move on to a new romantic relationship, or are you still grieving the end of your relationship with Yousef? The only thing I would advise against is moving on too quickly, before you are really ready. Give yourself some time to heal. And, if and when you do feel that you want to pursue a relationship with a long-distance boyfriend again, I would encourage you to have at least a couple of in-person visits (like Hussein suggested) before you get too serious again. You want to make sure that you make a good couple in RL and that you are equally serious about one another before you fully invest your heart again. I wouldn't want to see you get hurt a second time, like you did with Yousef.

Best of luck!
