Should I reach out to him?
	
	
		History on this story: About a year ago my boyfriend contacted my sister for my grandmother's address (I was at my grandma's for the holiday & my sister was still in town).  Well, my sister provided my boyfriend with my grandparents address to send me flowers, but I also found out that they also had a long conversation through email & text messages that same day (I know about the email because she told me and sent it to me, but she also cut parts of it out and she denies having it now).  The conversations started with jokes and discussion on about how I would react to receiving flowers from him while I was out of town.  They also talked about career goals and so on. My sister called me later that day and said that my boyfriend asked her out to dinner/lunch to discuss helping her with her career goal (he is in the profession that she would like to be in).  At the time I automatically did not believe my sister. She and I have never had a good relationship (we are a year apart).  I then nicely confronted my boyfriend and he totally denied it and wanted to confront my sister, but because I didn't want a big fight about it (and the fact that I know my sister is a liar) I explained to my boyfriend that she and I do not have a good relationship and I asked him not to reach out to her anymore because she would twist the story and make him out to be the bad person... when I know she is the one who is really up to something. 
The other day: He sent her a text message (he has her number because I called it from his phone one time) and asked her if I had made it home safe (I was driving back home from out of town). I was not able to call him myself and tell him my status because my cell phone died. She responded by just telling him that my cell phone must had died because she couldn't reach me either. Well, once I got home I called my sister because she left me a message on my voicemail. She explained to me that he sent her a text message and that she responded. BTW... I had also asked her prior to his text message to not respond to any messages whether it is through emails, texting or phone calls. I asked her why she did that and she didn't really have an answer. So when my boyfriend called me I kind of went off. I was like why are you contacting my sister after what she did last year? He was like I was worried about you, but what I don't understand is why doesn't he call my parents? They would know where I was because I would call them before anyone.  She lied on him last year…why would he put himself in the position again to possibly get lied on again by her.  It’s an uncomfortable position for me and I honestly wouldn't mind if this ordeal didn't happen last year (that they contact each other for the sole purpose of me). He then went off on me told me that I was immature and had low self-esteem. I also, recently asked my sister about the situation again and she has now changed her story and said that he didn't ask just her... he asked to help her meaning... I would be present as well. I have decided long time ago to limit my interaction with her not only because of this but because I can't trust anything she says. It’s never what actually happens. I don’t know why she lies about stuff but she just does. Anyway, my boyfriend told me to never to contact him again and I don't know what I should do? Should I reach out to him or just let him go?  We have been together now for two years and I don’t want to let him go, but sometime when he is made he totally ignores me for days or weeks and honestly I don’t want try to contact him only to get rejected.  I love him, but I need him to listen to my requests no matter what. I do the same for him.  Do you guys see my reasoning why I asked him to just leave her alone? What should I do?
