Am I the only paranoid one?

[Glamourcide]

DH is starting to get a bit shirty with me. I've officially been back on the Pill for a whole month now, and I still won't let DH come near me without a condom on.
I know it sounds silly, but I'm really terrified of getting pregnant again. Until recently, I was adamant that there would be no more babies for us, ever, but recently that cluckiness has kicked in again and while I know I don't want to 'allow' another baby to happen, if it did somehow come about, I would probably welcome it. DH, however, still doesn't believe we have any more room in our lives for another baby, and I would hate to put him in the position of resenting me if I can't terminate a pregnancy, and I would hate to be put in the situation where I feel like I'm forced to 'get rid of' a baby *just because*, kwim?

But DH is upset about it - like most men he hates using condoms and is keen to just ditch them and get on with things. So am I, I miss DTD without them, but I just can't overcome my fear of being put in that position.

So I guess my question is, what other kind of contraceptive can I look at that is more 'permanent', but not entirely permanent, kwim? I won't use Implanon ever again as I had terrible experience with it as a teenager - I whacked on 30kgs and I believe it triggered depression. I worry that the injection will have a similar effect (but I admit I don't know much about it so someone please correct me if I'm wrong), and I just don't trust the Pill because it's one of the ones that has to be taken at the exact same time every day, and I don't have a set routine, so I'm constantly forgetting or getting behind schedule with it, kwim?
Of course DH point-blank refuses to get the snip, and often says that if our marriage doesn't work out, he might meet someone else and want to have kids with them... I could get my tubes tied but like I said, I'm kind of open to the idea of more kids down the track somewhere, and I've heard that tubal ligation can really stuff your body around and cause other problems...

I just feel a bit helpless - I want the 'perfect' solution but I know it probably doesn't exist. Am I the only one who is terrified of getting pregnant again, but not so scared that they're willing to permanently end their child-bearing capabilities? What do you do in this situation? What contraceptives WORK without horrendous side-effects? TIA for any help or advice! :/
