Me n my Girl pt. 2

We are on better terms, we talked about the things that made us mad and we DIDN'T ARGUE which shocked the hell outta me. We both agreed to just stick it out n if its meant for us to be together, then we will be. I know how I feel, n it's not lust, I'm in love with her. I love just being around her, I love talking to her. She does so much for me n alot of ppl think its a s*xual thing but its so much more than that. She makes me smile from the inside out. Yea we have our little problems n its not all her fault, I admit to my faults and sometimes its me. She says things at times that make me wonder so I ask. Is it anything wrong with asking a question. For the past 3 days when we talk on tha phone, we argue. So last night, we talked about it n agreed to not automatically jump into an arument, to calm down first and question the other on what was said. Hopefully that works. Sometimes she trips on who I talk to on tha phone. Becuz this girl that likes me calls me alot n she trips. But I don't trip when she talk to other females. I mean, b/c I trust her. And I trust that she won't mess up no more. The girl is cool to talk to but that ayne what I want so shouldn't Rea trust that? But at the same time, I feel where she's coming from. So my question is should I cut off contact with the girl or lie to Rea and say I don't conversate with her no more. But that's lying n Ion wanna do that. So what should I do?
