I need some advice and/or consolation... Sorry it's kinda lengthy

I started a vigorous graduate program that pretty much prevents me from getting a job (even part time... I would need a one day a week job). So I've been on my parents ticket since my saved money is drying up. My parents have been hassling me about selling one of my snakes (i still manage to pay for them myself, but they want to stop paying for other stuff). My boyfriend knows how much they mean to me and how important the hobby is for me and he always offers to pay for their care.

Were not married, nor do we live together (thought I'd like to think that's in the near future), so it makes me uncomfortable to let him pay for my pets like that.
I don't want to sell either of my snakes, but if I were to pick one to sell it would be the spider since I refuse to let go of Constantine.

To me, she is the most stunning looking spider, the only one I have ever loved appearance wise, and I'm wowed every time I look at her. But looking is all I can do. Despite a lot of effort trying to tame her down, she is extremely nippy, nervous, and frankly she's just not any fun. I feel like she would make gorgeous babies if I could breed her, but that's so far down the road (if it's even down the road considering I've got a lot of school and fund less years left to go). If I don't know if I will be able to breed or ever get a male, is she worth keeping?

Like I said, I love her and it would break my heart to sell her, and I'm worried that losing her would put a damper on my ambitions in the hobby. But I also need the money. I could always let my boyfriend take the financial obligations, but I'll feel guilty at the same time.

Any advice? Thanks in advance and Sorry its kinda a rant/whine/mopey post.
