Boyfriend hasn't said "I love you"... does he love me?

Well first off he sounds like he is developing an unhealthy obsession with you when he says "I don't know what I'd do if you left me" but besides that, most guys (myself included) avoid saying we love a girl because it can ruin a relationship if said too early. rushing him into it will throw him off and make him feel awkward about it, and becoming upset because he hasn't said he loves you won't solve anything. Let him get to it in his own time, or tell him you love him to see his response.

He could just be scared. My boyfriend, who I have been with for a little over a year..still hasn't said "I love you"..but, I am not going to push it. He has loved one girl in his whole life..But, she cheated on him and hurt him really bad. So, my guess with my boyfriend and your boyfriend, is that they are afraid of loving another person..and want to make sure that you will not hurt him like he was hurt before...for example, just breaking up with him..or cheating...and etc. I think he does love you...but, he may be scared to say it yet. He may also get his moments where he withdraws himself...I know my boyfriend does. I think its his way of protecting himself. He feels these feelings that he loves, and gets scared..so he backs off. I am not sure if your boyfriend does this..but if he does..it might be the same situation as mine. My boyfriend dated his last girlfriend for 2 years! And still didn't tell her that he loved her! I guess some people just need time...Good luck.
P.S- I wouldn't push it though, for him to say it. And, it might help, if you casually say it to him.

Give him time. When he says it, it will be for real.

As a side note: try not to pressure him into saying it. My cousin wanted her boyfriend to propose so badly, and she kept hassling and hassling her boyfriend. It turned out he had planned a big surprise proposal that would take her breath away, but on one particular day she was hassling him so much that he broke down and gave her the ring when she was in a fit of rage and showed her what he had planned to surprise her. She pretty much ruined her own proposal.

You might be doing the same thing if you hassle him to say "I love you." He wants it to be special. He wants you to know you are special and that he means "i love you" when he says it. So appreciate him for the shy, honest, caring, supportive, un-manipulative, great guy that his is. It will mean more to you when he finally does say it.

I think every time he says " I like you" it really means "I love you" he's just afraid to say it in fear of your reaction from the looks of it... I had a saimilar experience.

Everytime my boyfriend held me, he'd whisper "I like you" but all this time, he was waitng for me to say how I felt about him. So when I kept telling him "I love you, for who are" he replied "So, that means you love me?" and when I said I do, he whispered "I love you too" and not "I like you"...

i think he loves you, he's just afraid..

He might not actually be in love with you since he`s not actually said "I love you" even though you`ve been together for a year. But like you said, he`s a shy guy, give him some more time and if he still doesn`t say it, then you should ask him about it. Some people have a hard time expressing their feelings, I know I do when it comes to relationships.
