I'm an ox but my boyfriend is a horse. S.t. about him keeps bugging me.

He's a great provider, demonstrates his love in lots of ways but something about him 'bugs' me. I think I tolerate him more than I love him. I used to love a boy who is a 'dog' and I haven't gotten over him but this new bf (horse) I'm having trouble completely falling in love with. I feel more like his roommate but anything more absolutely makes me ill. I'm feeling guilty this horse is 'good' to me. It seems the less we spend together, not only is ok by me LOL but I actually like it. I think my former boy (dog) died, I think of him all the time. I'm good friends with snakes and pigs which I'll gladly spend time with than the horse. Ugh. Please help me understand me.
