It definitely sounds like something is bothering him. I don’t think you need him to tell you that for you to figure out that things have changed. But you can’t make someone tell you what they don’t want to. And since you’ve already asked him multiple times, the best thing you can do is to be there to listen if he wants to talk. Being clingy or needy isn’t going to work — it’s going to make things worse.
However, his increased disinterest is a sure sign he’s losing interest. I know it’s scary to think someone you’re attached to is losing interest, but all you can do is be the best girlfriend you know how to be, and if you’re doing that and he’s STILL not interested, then you have to accept that he’s lost interest. 🙁
I hope that helps. Let me know how things go, and please follow me @AskAprilcom on Twitter and on Facebook at this link: [url][/url].
