For some background: I met him on the first day of university. We became a couple and dated throughout the first semester. He introduced me to his family and was very affectionate in the beginning. Midterms and finals came and we spend less time together, of course so we could focus on getting good grades. Before summer came, he told me "be sure to reach out because I tend to forget" This is true...sometimes it seems he ignores me for days, and even sometimes in person he will see me and walk past me without acknowledging me. Why does he do this? Why is he so hot and cold? Now that it is summer, I see a dwindling in his communication towards me. Now its been about 2 full days with no communication and before...just small texts here and there that that I would initiate and he would end by just not replying. When I have confronted him about this behavior in the past...he always has a reason and its always "I love you, I want to be with you." and then he will reach out more for a couple days after. I also should note that the last time I saw him in person, I asked for his phone because I wanted a specific picture of us he took, and he weirdly said no and that he's deleted all our pictures. granted he ALWAYS only had 10 pictures on his phone...but usually he would just hand me his phone. I am not sure what to think and I am super confused. Should I just leave the relationship?
