<human>: I go on an annual camping trip with a bunch of friends. I broke up with an ex last year and I'm dating someone new this year. 

I had already planned this trip and just for context, there are about 30 to 40 people that go each year. Some of which include my ex, her brother in law, and two of my brothers. Andy (the brother in law)  and I are both getting into bicycle touring which is basically an extended bike ride (from days up till months/years). Him and I planned to ride our bikes to the camp grounds (across the state which is only about two days).

My current girlfriend mentioned that she didn't want me to go on the camping trip since my ex would be there. I agreed. I then mentioned that maybe I would just do the bike ride there then ride back (I wouldn't even see my ex). She didn't have much to say about that but I thought she was pleased that I wasn't seeing my ex girlfriend.

Fast forward to tonight. Someone asks if I'm still training for the big bike ride (it's still two months away)  and I said yes. My girlfriend has a little freak out saying she can't believe I'm still going on the bike ride and that I'm hanging out with my ex's brother in law. It got a lot more verbal than that but I'll leave that part out for now unless someone thinks it's relevant. It was pretty bad though.

So... was I wrong? Is my ex's brother in law off limits?  I thought I was doing the right thing by not going camping. I still think that but is dropping the bike ride necessary? I was really looking forward to it.

Can you give me the gist of the text in a nutshell?
<bot>: already agreed to not attend a camping trip due to the presence of the ex. Now I'm being asked to avoid the bicycle trip that the ex isn't involved with.
