I can't help but feel that I'm second best to my boyfriends parents. Please help?

I understand guys need a lot of family time and guy time, that's perfectly natural and I respect it. And I'm glad my boyfriend has a good relationship with his parents and has good friends... but. ..

I feel I'm second best. it's been 2.5 years that we've been together and I just feel like I'm his second choice. We agreed that because we're young and don't have much money that instead of buying anniversary presents for each other we would make them... I tried really hard and spent a lot of time on his present, I think he spent all of 5 minutes on mine. 

He's now going out and buying his parents an anniversary present...

I just think it's a bit weird. I don't get it. I feel that in his eyes the plans we make with each other aren't as important as the ones he makes with his dad or other family members.He says I am part of his family, but I don't feel I am. At times I feel like an inconvenience. it's horrible.What do I do? Any suggestions? Has anyone else had a similar situation or felt this way?

Thank you
