When i was in UK the same happened to me, I am not afraid of spiders so when i noticed a small one wandering around living room, I left him too it, I say he, coz it felt like he was a he,

he he! anyway after seeing him a few times I called him intsi (can't spell that) every night while I was lounging on settee watching tele he would come wandering in have a walk round and go back towards the kitchen. After following him one night I saw him go into a small hole at the corner of the skirting board. This carried on for 18 months!! obviously growing all the time he grew quite large, he got so used to the fact I was not going to harm him, he took to coming out of his hole when i was washing up just sitting there as if watching me. I know this all sounds crazy but I
swear it is true, and I don't drink! One night he did not come for his usual wander and that was it, he never came again, Oh, I'm filling up. So Sabrina,you are not going crazy, and trust me you will grow to love him/her.
