Name changed.
BF & I are both 25. Been together 3.5yrs, don't currently live together as work patterns are very different, but plan to in the next year. Spend about 4 nights a week together. No kids. & I've realized he never sticks up for me or is on my side.
An example
On Saturday we went out to the nightclub he runs. He's there every week, I rarely go. When we arrived and I was talking to a mutual friend, a young girl (late teens) came running up and hugged him, very animated and friendly. When I went over, she gave me a filthy look and stalked off. She then gave me the stink eye all night and blanked me when I said hi. Literally looking me up and down with a raised eyebrow. Thought it was highly amusing, I asked him who she was and said about her glaring at me, and he immediately sprang to her defence, saying I was wrong, she's just a child, she was shy and so on and so on. She's not a child - most 18 year olds in nightclubs are perfectly capable of trying to seduce men. Later he picked a fight with me and accused me of being jealous and possessive.
His sister is really rude to me and he says nothing. When I fell out with a good friend he refused to back me up, saying she must have her reasons. (she stole money from me twice). If I ever make a slightly negative comment about a friend he immediately defends them. I don't need a knight in shining armour but am I unreasonable to expect a long-term partner to be on my side sometimes?
