Is this normal after a break-up?

please keep anon due to my ex who is on here... so me and my boyfriend of two years (we're both 20 - first love for both of us, lost virginity to each other, went abroad together etc) broke up around 3 months ago due to lack of trust due to being at different universities. we honestly (and probably stupidly) thought we were going to stay together forever as we seemed so compatible and I never had a dull moment with him, so for the first month or so after we ended I was so devastated. but since then I have found myself feeling very detached from guys in general. I have been texting a few people and been asked on a date or two but I just kinda feel nothing. I don't want my ex back but at the same time I don't want anyone else :K: I am much happier nowadays and things with my mates are good and am excited for the future but I feel scared at the thought of another relationship, cause I don't want to get hurt again and spend so much time building a life with someone and caring so much, only for it then to go down the toilet. don't really know why I am posting this, seeing as I don't have a particular question, I just feel kind of confused as to whether what I am feeling is normal seeing as I have never been through a break-up before... :$
