<human>: Can you provide a brief rundown of the text in within 3 sentences?

My boyfriend and I have been together for a while now. We're both still in college. We've done so much together already, more than we have in any of our previous relationships. We fit perfectly together. Last summer, we have already even lived together. We decided to try it out, but we both agreed it wasn't going to be permanent. We both split everything half and half, so neither of us had to pay for one another. Of course it was a bumpy beginning, since it was the first time for both of us. This winter we are actually traveling to Germany together (we live in the US) to visit my family for Christmas. It will be his first time. His parents are perfectly okay with that. After that, his family let us stay for a couple weeks at his family's summer house. His family has always adored me. I get along great with his little brother, his father you can clearly see loves me, and I fit great with the mother. We would have a glass of wine together and chat, and she buys me a nice bottle of red wine every now and then, even though she does not like red wine at all, so she knows its just for me. I've stayed over at his house several times before (we live 4 hours apart away from college) and they seemed happy to host me. The longest I've visited there was a week. 
Anyway, about a month ago my boyfriend and I were discussing when we would officially move in together. Apparently his mother told him that she does not want us living together during college (which is understandable) and she said that she will cut off taking care of him financially if he does (which caught me off guard quickly). I understand completely if she would have said "I really would prefer you didn't" but they are not the kind of parents to say "If you do something, I'm not going to support you financially anymore". 

Now I am absolutely baffled about how his mother feels towards me. Nothing has changed, but I'm baffled by this response from his mother. 
I'm not sure how to react to this, or what to think.
<bot>: boyfriend's mother's reaction suddenly very negatively strong towards me, nothing has changed. Don't know how to react to this.
