platonic friends

i have two very close guy friends that have stepped up as the brothers in my life since my actual brother has done a very poor job. one has been in my life for 5.5 years, the other for 4, so they have been around for a lot. i'm not a girl who has lots of guy friends. just a handful really...but these two are my rocks. so loyal that it makes the guys i date wonder. they do a good job of befriending boyfriends in order to make them feel comfortable. H seems very wary of the situation though, which i can understand since i don't know how i'd feel if the tables were turned, but it's hard to explain to him still. yes, i dated one of these guys for a few months when i was 18. we haven't kissed in 5 years though, or even come close. i keep assuring H of this. that there are no feelings....but he doesn't get how a guy could sleep on my couch and not be tempted to come upstairs. haha. hopefully in time he'll learn to love these guys too and understand that sometimes things are completely platonic.
