<human>: Give me a shortened version of the text

Background: we're both college students and have been dating for close to three years. Both of his parents absolutely hate me and it's always been a problem, but it's starting to get out of hand. I apologize in advance as this is probably going to get long and rambly but if anyone has any advice I would really appreciate it.

His mother literally didn't like me before she even met me. I honestly don't know why she doesn't like me, but she's very extreme about it. Every time I've seen her she takes one look at me and walks in the other direction; she won't even speak to me. She literally gets mad at him if he does anything with me and will stop talking to him for days because of it. His father actually gave me a chance and took my boyfriend and I to a show when we were in high school, and decided after that that he disliked me. I don't have as much of a problem with this, since he actually made an attempt to get to know me (though it was a rather small one), though I do think it's because he misconstrued my shyness as being unfriendly. 

Obviously this has always been a problem since his parents have always disliked me, but it's started to become a bigger problem. It's at the point where he'll sometimes choose to stay home rather than spend time with me because he's afraid of making his parents mad at him. We have a great relationship otherwise; his parents are really his only problem. I can see our relationship going far (maybe even getting married) and I know this can't stay this way. I'd hate for such a good relationship between two really compatible people to end because of something like this, so if anyone has any advice or similar experiences to share it would really be appreciated.
<bot>: My long-term boyfriend's parents hate me for (seemingly) no reason and I think it's time to do something about it. Please help.
