<human>: Can you provide a brief overview of the text?

My boyfriend and I have been together for 3 years. I had an old friend from high school who just got back from serving in the middle east. He started talking to me on facebook, and said he had moved back to Houston. He said we should catch up and I thought it was a great idea. My parents have moved out of Houston to California, so I didn't have a place to stay, so he offered that I could stay at his house. 

I told my boyfriend about this, and he said he didn't want me to go. I asked if it was because he didn't trust him, and he said, it was that and that he didn't trust me being in that situation as well. He said after a few drinks or in the wrong situation, anything could happen, and he would hold me equally accountable. 

I don't know how I feel about that. This sounds controlling, but I am not sure if his concerns are valid. I feel like he is being insecure. What do y'all think of the situation? Should I tell him after 3 years I have earned a little trust?
<bot>: Boyfriend doesn't feel comfortable with me meeting up with an old friend and staying at his place because I have no other options to stay in the city.
