I understand how uncomfortable that could make you. Getting the odd message here and there is fine -- romantic, really, to get an "I love you" out of the blue. But getting a message everywhere gets not only repetitive, but uncomfortable. I'm a fairly closed off person -- I can be affectionate in my own way, but it takes me a while, and I don't respond to a ton of affection very well, not at first, and DEFINITELY not in the levels you're getting (if you want to call it affection ... maybe obsession is a better word?).

If your boyfriend was in this abusive relationship where he was forced to check in 24/7, it's possible that he doesn't realize that he doesn't have to be that way with you. Have you talked to him about that relationship at all? I think it might help if you clarify that you are not his last girlfriend, that you are not like her, and that you don't expect him to message you all the time -- in fact, you don't want it. Maybe suggest some kind of set day or time when he can call you. Say something like "Why don't you call me Saturday, some time after 4?" Or tell him that YOU'LL call HIM at a set time. Maybe if he has a little more structure, a specific time when he knows for absolute certain that he can reach you and talk to you, things will be a little easier on him and he'll be able to relax a bit.

Still, do be careful. Others have made a good point -- if he is REALLY making you uncomfortable and you feel that he's smothering you, don't stick it out. You don't need that kind of pressure in your life, and chances are what HE really needs is some help.

Hope this helps.
