I'm having trouble putting my feelings into words, it's hard to describe, but I am worried and seeking advice so I'm going to try my best. Is it normal to have like phases in a relationship where you just feel bored, uninterested, or don't feel like you love that person anymore? I've been with my current boyfriend for a year and 7 months. For the most part he is amazing to me, I know for sure he loves me more than anything. I say for the most part because as any other person on this Earth he has his minor annoyances and flaws that upset me, and we fight an average amount. Sometimes I have this phase where I'm crazy about him and can't stop daydreaming about our future, then sometimes I just feel like I'm falling out of love for no reason. Maybe it's not that, it could just be a different feeling I don't know how to describe, but isn't really falling out of love. We had a rough spot from July to December where I was treating him bad without even realizing it so we were fighting like once a week but we broke up for a week, I apologized etc and we have been fine in that sense. For some reason though, right now, I'm getting that kind of falling out of love feeling. I left for vacation last Thursday, and since then I've felt bored with him and pretty much everything he has said or done has irritated me. Sunday I left my grandparent's house in Maine and we met up with some other family at Martha's Vineyard. For the first day or so I was thinking how great it would be to come here with him and all the things we could do together and daydreaming about having our honeymoon here when we get married, but after that and today I've kind of just wanted nothing to do with him. This feeling is worrying me and making me uncomfortable. Can someone give me advice and tell me if this is normal or not? Maybe I am just worrying too much, and I'm so worried that I'm making myself feel things I'm not. I often worry that for whatever reason we won't work out, I worry I'll want to have an affair when I'm off at college, I worry that we'll never have time for each other and break up, I worry for whatever reason he'll just want to end the relationship or vise versa with me, again the whole falling out of love thing. I know all my thoughts are jumbled and we have a great, strong, and healthy relationship for the most part... which is why I don't know why I feel this way.

This is so normal I don't even know where to start.
They key fact here is your age. You mention going off to college, so can I assume that you just finished high school?
Teens are going through a million changes about what they like and want for the future, and this is reflected in how they feel about relationships, which can turn on a dime. They are learning about what love really means, and the stages it goes through after romantic love wanes and evolves into something based on shared struggles.
You sound like you have a pretty understanding mind for a teen and I think you will do fine.

All that you're describing is exactly what I have felt in every relationship. I was with a guy for two years and I felt these feelings too but since I don't think I was ever really in love with him well then I thought that was the reason why. But it has happened again two or three times with my current boyfriend. Im crazy about him, we've been together for a year and we already hope to spend our life together. I know people might shake their heads thinking "you don't know that" and of course we don't but that's just to prove how crazy we are about each other. Like you, I daydream a lot, we sometimes daydream together, he stayed in my city to do his internship, I'm following him abroad for a year to Australia (he left yesterday and I'm meeting up with him in september) and I've started to feel these feelings of boredom, of feeling like maybe I'm better off single, if I don't think about him too much during the day I'll start wondering if I'm still in love, etc... It's weird. I try not to think too much because I know I'm able to convince myself of stuff that sometimes isn't true, if that makes any sense ?
Anyway, hope you'll get more advice, as it will help me too lol but just to let you know you are not alone ;)

Thanks for the advice. It is making me feel a lot better about my bipolar feelings with my boyfriend haha.
