<human>: My boyfriend and I met summer of 2012. Our relationship was complicated by the fact that he was one of my close friends exes (I didn't know them when they were together, he and I just got wrapped up in it, excuses, yaddayadda). Anyways, after about half a year of dating, he started to pull away, became distant and, over the course of a few weeks, we broke up. He claimed we were just having trouble with the long distance, but also alluded to a general uneasiness/restlessness. It was painful, I didn't want to break up. Of course, over the next half a year of not being in contact, I realized it was good we had the distance. He can be very focused on himself.

Anyways, that half a year goes by, we get back in contact, fuck each other's brains out, and, over the course of a few months, get back together (side note: I was reluctant at first, and had to rebuild my trust, which was made more difficult by the fact that he had been seeing my friend, his ex, again briefly). Now we've dated for 7 or 8 months, he expressed doubts recently (similar to those that broke us up before). It made me feel like he didn't want the relationship , though he claimed to still want it deeply.

After a few days of feeling this way, I sent him a letter basically ending it. On some level, I wanted him to fight for me - I wanted to see him put in the effort, especially since he had seemed unsure before. He hasn't done anything. This is sad. Some part of me wants to preserve the possibility of him making some grand gesture to win me back. But should I just work on moving on? Especially since I already had some other doubts about him this time around.

Summarize the given text in a few sentences.
<bot>: My boyfriend has the same ambiguous doubts - I want to keep open the possibility that we could be together, but does that show no dignity?
