I broke up with my ex-boyfriend almost 2 years ago. We were dating for 2.5 years, mostly a long distance relationship. I found out that he went on a business trip with an female co-worker and they shared the same room. When I asked him why he didn’t tell me, he said there were 2 beds and they didn’t do anything.

Long story short, we broke up, he blocked my Facebook and still does. After a year or so, he emailed me to catch up, but I said nothing. Anyway, I’m dating my current boyfriend for almost a year now and we are very happily in love. However, whenever it came to him or I saw his Instagram post and his girlfriends, there is a feeling that I cannot describe. But I know it’s definitely not love, not friendship, nor happiness.

So I want to ask for advice how to get rid of that feeling, because I know it is unfair for my boyfriend, if my mind still thinks about my ex, even just for 1 sec. I don’t want to see my ex ever again if by any chance we meet, I want myself to walk past him like I don’t know who he is. Please give me some advice.
