Can a fetish just stop by itself?

This is maybe a pretty weird question, so I'll make it clearer.
I'm 19 and I have had a foot fetish for a really long time, even before I started discovering my body I remember feeling attracted to feet. However, two week ago it just stopped. I just stop being sexually attracted to feet, and all the fantasies(if you don't know this fetish well, these fantasies are like massaging feet, worshipping them or other stuff. Basically, when you have a foot fetish you like to submit to someone(a woman in my case) by being at their feet) that used to attract me now leaves me pretty blank(and I actually think what was attracting was more the submission than the foot itself, as I never felt attracted to footjobs, and was just attracted by foot worship, and sometime even the words "obeying" or "submission" or "worshipping"). I think I know why it happened, I started wanting having a real relationship with someone, wich really motivated me to get my life together and make an effort to become a real adult that can take care of himself and also to make an effort to look nicer and loose weight, and as I applied all those changes in my life I think I just started to see my fetish as something unhealthy, and I stopped wanting to be a slave and started wanting a relation where I'm on the same level as the other person because that's what love really is to me.
You may be wandering where my problem is since I sond like I'm living the happiest time of my life right now. In fact there are two problem:
1- I didn't even know this could happen before it actually did because before now I never felt bad with my fetish, and it's honestly kind of scarry wich bring to the next problem:
2- I've not been sexually active for two week now, wich may not seem so long for some of you, but I can tell you that before this happened I was really adicted to porn and masturbated at least one time a day(I know, I was scum). It's probably because I'm not sure if can really be turned on by a classic sexual intercourse, as I rarelly had any fantasies about them and I'm really scared to have one(wich is, I think, part of the reason why I developped this fetish in the first place).
As you can see these are pretty scary times for me, I really don't know what will be the outcome of all this, so if any of you guys think they can help me or if you just wanna talk about this then don't hesitate to respond, I would really appreciate it.
I know this is already a long message, but on a final note, if you have any fetish, you don't have to feel ashamed by this message, I don't care and I don't think you are disgusting for having or should get rid of it, if you like it then it's good for you mate .
