<human>: we were going out for 3 years and had a great relationship. Each other's first love, best friends, etc. However, I (f23) left to go on a vacation with my friends for a month and suddenly out of the blue he (m24) called me a broke up and stated that he was confused about the future and felt its in our best interest if we stopped seeing each other. Needless to say, I was shattered and felt abandoned because I had not seen this coming and was as shocking to me as to any of my or his friends. After trying to repeatedly talk to him about it and get to explain WHY he did it, he decided that he wanted to give us another chance and that we should get back together. I was obviously overjoyed when he said that but since then I have put it off for a month and feel a little afraid in getting into a relationship with him again because I feel that he might ditch me again and the next time I might not be able to fight for us. But my question to you r/relationship_advice is that how do I convey to him in a mature way my insecurities? when I tried talking to him the last time, all i could say was that I was hurt and upset but I just couldn't communicate that to what *extent* my trust has been lost. Please help me out!
