Confused 😩

So my BF & I have been dating for 11 months next week. We met last summer. I have 2 kids & he has 2 kids. Kids get along, his daughter is same age as mine & our boys are same age also. Things are going great. He loves me, I love him, we even have been talking about moving in together & eventually having a baby together. The only issue I’m having is I have these moments where I get so irritable, I don’t want to hang out. If we don’t see each other for a few days, I’m ok with that where he’s not. Tonight he decided to surprise me & I open the door, greet him with a kiss & go back to watching my movie. We chill on couch, watch tv but Then he gets upset because he expects me to be more loving & excited that he surprised my But I’m already irritable.....

I’m due to get my period this week & I’m thinking maybe my hormones are out of wack because I took my IUD out 2 months ago. We been having sex, ttc, But I have these moments where I’m just not feeling it, (as in not wanting to hang out) then I start thinking about things I want more out of this relationship, like for example, I’m not materialistic, however I do like the “Lil things” too, like flowers for no reason, a card, Lil gestures like that. But I don’t know how to tell him without hurting his feelings. I always shut down. He’s very open with me with his feelings & I shut down. Another words our love language is totally opposite & I don’t know what to do. I know this relationship can go further I just don’t know what to do with how I feel sometimes. Any one have suggestions or advice. 😩😞
