He's the one asking for more

Over the past year my s.o and I have been having relationship issues. It's been tough. Some things I'm still trying to get past. Nothing to bad was done, just a few things I found out about that broke my trust. (Having female friends Inwas uncomfortable with, things like that) I was distancing myself because I was considering leaving him. Before we started to talk out our issues and really communicate, we were both pretty bad. We both didn't make time for one another and without knowing it all of the sparks had began to diminish. Now he's really trying to make me fall in love again. Bringing flowers and chocolates home for no reason. Spending quality time with me and taking me on more dates. I can't say it was just him who put a wedge in our relationship because I can admit I stopped trying too. Now he's the one who sounded like me about a year ago, he's asking for more attention and makes comments abour how I can go a whole day without even kissing him. He said it feels like I don't love him anymore. I told him last night I'll show it more, he said please. I know I'm still angry about some things and I'm still hurt, but I see he's really trying. I can't say he's not. I just feel so stubborn for not being able to let things go and I think now if I don't I'll really push him away. I really want to let it go and give my all and put 100% of my heart in again, but I'm scared of always getting hurt. I have a wall up and I don't know how to let someone fully in.
