<human>: So me and my boyfriend have been together since we were 14, and he has always been the jealous type. I've tried really hard to stop it from bothering me, as I'm not the jealous type at all. It hasn't been a major problem until last week 

When with a group of friends, he went through my phone and read my messages. He then started questioning me on "who's this? Why are you messaging him so late?" And I was mortified. He embarrassed me so much in front of everyone, and he made his jealousy everyone's problem. I left immediately, and we had a conversation about boundaries and privacy

Ever since then, I've felt different. It caused alarm bells to ring in my head! He's texted me when I've gone out telling me to "be careful" and to "not let other men hit on me" and it's a very ugly quality in him I don't like. I told him his jealous is pushing me away, and he says he's terrified of causing issues between us and wants to change 

I've also started to get feelings for another guy, although he's a lot older then me and I don't think anything will come of it, just the fact I've started to get strong feelings for someone else for the first time in our relationship is causing me real problems

I care about him so much, but I'm not sure if I want to be in this relationship anymore. I don't know how I'd be without a boyfriend, as I've never really been without. I'd like to also add I'm going to university in September, so that is also going to add strain and possibly make his jealousy worse. I don't know whether or not to end it now, or wait it out and see if he changes or I feel differently

Give me the gist of the text in a nutshell
<bot>: very jealous boyfriend read my messages in front of a group, changing how I feel about us. I've also started getting strong feelings for an older guy. Should I end my 4 year relationship?
