Insecurities

hi i've been dating my bf for almost 2 years however i am still rather insecure with this r/s because of what he did. i hope to get a clear and legit advice from ppl who has experience it or even know whats the best way for me to do/feel better. just 2 years back, i got to know my bf through university. back then we hung out alot before we got together. to be exact it took us about 8 months officially together. however, during the start of this r/s i found out(with solid evidences) that he was actually dating a girl just during that 8 months when we were hanging out. he didnt even let me know about this girl. what's worst, he brought this girl home right after they got together just within a week. to top it up, they only knew each other for a wk and they got together. it disgust me. the underlying problem is, since he got together with that girl and brought her home so quickly, why isnt he doing the same to me? he took 1.5 years to bring me to his place. we quarrelled about it and he said i was pressurising him. but from whatever he had done in the past i just don't trust him 100%. i tried asking him why he took so long to bring me home, he said he already wanted to bring me earlier, however he decided not to because I'm pressurising him which in fact, I AM NOT. only 1 year later then i popped that question. how could he bring a girl he barely knows home just within a wk? and after getting together with me for 1.5 years then he decided to bring me over? i donno if he truely loves me. please advice on what i should do.

Based on what you wrote, I dont trust this guy. If he brings home a girl in a week, and goes out with her and doesnt tell you about it, thats a big red flag. If he loved you, he'd listen to your concerns and be honest with you. leave him now!!!!
