<human>: Who said it first, and was it reciprocated?  If it wasn't reciprocated, was it ever used against you or vice versa?

I'm a 24 year old male who has been in a relationship with a 29 year old male for 10 months.  My boyfriend told me he loved me after 5 months or so, and I didn't say it back.  At the time, I saw a lot of potential in him, and I still do, but he was just really needy and clingy.  It was a huge turn off.

I was still happy to be with him and was planning on being in it for the long haul, but every so often, he'd state that I didn't love him.  He equated saying "I love you" with a stable relationship and thought that I didn't value it as much as he did.  He'd say that every other guy he'd been with had told him they loved him after 6 months or so; and made a point that I told my last ex (who I'd been with for 3+ years) I loved him after 6 months.  If it matters, he's never been in a multiyear relationship.

I can't say for sure if I would have reciprocated sooner if I didn't feel like I were being emotionally manipulated.  I wasn't sure if I really loved him or if he had just guilted me into saying it.  Lately, he's been extremely distant and we haven't had any intimacy (and definitely not for a lack of trying on my part) because he thinks that I'm just using him until "something better comes along".  He just seems...resigned.  I've only told my current bf I love him recently because we've been talking about breaking up and I realized how important he is to me.  But now it seems too little too late.  So what should I do?  How should I proceed to make things work, or should I even try?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My bf told me loved me after 5 months or so, I didn't reciprocate till recently.  Now he holds it against me.  What do I do?
