<human>: Can you provide a brief rundown of the text in within 3 sentences?

my ex (m24) left me (f22) 3 weeks ago after dating for 2 years. 4 days after we broke up he told me that he has been talking to this girl on tinder exchanging nudes.  today i have learned that he has been seeing someone we went to high school with. he has been sending her pictures of hearts and their initials together. how did he get over me that quickly?

he has also told me that this breakup has been hard on him and he has yet to sleep in our bed since i left (which was 2 weeks ago). he also tells me that he cares about me but not in the same way. although he told me he loved me 3 hrs prior. he also says that he wants to remain friends and that we will see each other again. 

i find it weird how he has been telling me these things if hes with someone else. oh... she knows about me... she blocked me on facebook although i dont know her or spoken to her. wtf is going on??
