<human>: Provide a brief overview of the text.

A month ago I broke up with my boyfriend of almost 3 years. It was amicable, I wasn't really ready for a relationship and he understood. However, prior to our getting together in junior year he was a total asshole and 'friend-bullied' (essentially bullied him but thought he was friends with my friend and my friend was too nice to stand up to him) my best friend. Because he was an asshole he had practically no friends, then around the time we started dating he came into our core group (which includes my best friend). And he was rather co-dependent during the relationship, no real desire to see other friends outside of me (and upset when I wanted to see friends outside of him). 

Now we're both back for spring break, which happens to be the week before my best friend is going to leave for six months. My best friend and I are far closer than my ex and my best friend, however my ex doesn't have anyone else, really, and has been taking the break up badly because he refuses to let himself grieve. My best friend feels bad and has essentially replaced me for him, it seems he is spending most of most days with him, so I have no time to see my best friend. 

I understand where my best friend is coming from but it really hurts that he is spending most of his time with my ex when I have always been closer (and a better friend) with him and I feel like he is choosing him over me. But I also know he is in a tough place, I can't decide if I should talk to him about it so I could maybe get more time with him or if I should just try to get as much time without kicking up a fuss. I don't want him to only spend time with me, it's just that he's seen my ex for several hours each of the last three days and I have seen him for two on one day. I also don't want to make his last days home stressful/awkward because of us/me.
<bot>: Recently ex-boyfriend has fallen back on my best friend right before he is about to leave for six months, leaving me almost no time with him. I don't know whether to talk to him or just leave it be.
