<human>: My boyfriend of a year just told me that he only started dating me because he thought he was gay and thought that other people would think he was straight if he was with a girl. 

He went into our relationship intent on just using me, but later realized that he really did like girls too and was actually bisexual.

He keeps flip flopping by saying how he's so so sorry, but then saying that he thinks we've been dating for long enough that I should be able to forgive him.

I understand he was a different person a year ago, but I feel like it will be hard to trust him again.

Give me a shortened version of the text
